Chapter 3: Methodology
3.1 Introduction
The load distribution in tied conditions of reinforcement cages can be addressed using several different approaches. One approach is to use a beam-on-elastic foundation analysis. This method uses a beam with a distributed load applied at the center of the beam and an elastic foundation at the ends of the beam. The elastic foundation is used to simulate the tied reinforcement by using a stiffness coefficient which represents the load-carrying capacity of the reinforcement.
3.2 Approach of the Research
The stiffness coefficient is calculated using the appropriate equations for the type of reinforcement being used. Another approach is to use the finite element method. This method involves dividing the reinforcement cage into several elements, each with its stiffness coefficient, and solving for the load distribution among the elements. The stiffness coefficients are determined by solving the appropriate equations for the type of reinforcement being used.
Finally, the approach is to use a combination of the beam-on-elastic foundation analysis and the finite element method. This method uses both methods to simulate the tied reinforcement and the load distribution among the elements. This approach allows for a more accurate representation of the actual load distribution among the elements.
Figure 3.1: Research approach
In LUSAS software, the approach of the load distribution in tied connection of reinforcement cages when lifted horizontally to vertically can be achieved by applying a tie force and a vertical force to the reinforcement cages. The tie force will ensure that the cages remain in a fixed position. The vertical force will ensure that the load is evenly distributed among the reinforcement cages. This can be achieved by using the LUSAS Modeler’s tie force and vertical force elements. The tie force and vertical force can be applied to the reinforcement cages with the help of the LUSAS Modeler’s load panel. Once the forces are applied, the results can be observed in the LUSAS Modeler’s results panel.
3.3 Tools and Techniques
The LUSAS finite element software offers a variety of tools and techniques for analyzing the load distribution in tied connections of reinforcement cages when lifted from horizontal to vertical. Some of the main tools and techniques include, The LUSAS software uses FEA to simulate the behavior of the reinforcement cage under load. This allows for a detailed analysis of the stresses and displacements in the cage, including the load distribution in the tied connections. The lifting process of the cage may involve large deformations and nonlinear behavior of the materials. LUSAS software has the capability of performing nonlinear analysis to simulate such behavior.
The software also includes contact analysis tools that can be used to evaluate the behavior of the connections between the bars in the cage. This includes the load distribution in the tied connections and the behavior of the connections under load. The LUSAS software can perform both static and dynamic analysis. Static analysis is used to evaluate the behavior of the cage when it is lifted from horizontal to vertical at a steady state. Dynamic analysis is used to evaluate the behavior of the cage when it is lifted from horizontal to vertical at a varying speed (Fallah et al. 2018).
The LUSAS software provides a variety of visualization tools that can be used to display the results of the simulation, including bar graphs, contour plots, and deformed shape plots. The software provides a variety of post-processing tools that can be used to analyze the results of the simulation, including stress and displacement analysis, comparison with design values, and evaluation of connections (Motta et al. 2019). It is important to note that all the above tools and techniques should be used by an experienced engineer familiar with the software and the structure that is being analyzed. The results of the simulation should be used in combination with other design tools and engineering judgment to make informed decisions about the reinforcement cage.
3.4 Data Collection
The LUSAS finite element software is used to measure the load distribution in tied connections of reinforcement cages when lifted from horizontal to vertical. The software is used to create a 3D finite element model of the reinforcement cage, and then a dynamic analysis is performed to simulate the loading process. The model will be used to measure forces at the connection points and calculate the load distribution in the ties. The data from this analysis can then be used to compare the expected load distribution with the actual load distribution (Balada et al. 2019).
This analysis can be used to determine the adequacy of the connection design and to ensure that the reinforcement cages can safely support the loads when lifted from horizontal to vertical (Van Rossom et al. 2019) The first step is to create a 3D model of the reinforcement cage using the LUSAS software. The model should include all the relevant geometric details of the cage, such as the dimensions of the bars, the spacing between them, and the location of the tied connections. Next, loads and constraints need to be applied to the model. The loads would include the weight of the reinforcement cage and any external loads that may be present during lifting. The constraints would include the fixed points on the cage where it is supported during lifting (Sparling et al. 2021).
The results of the simulation can be visualized in a variety of ways, including bar graphs. The bar graph will show the load distribution in the tied connections of the cage, which can be used to identify any potential problem areas. It is important to note that the accuracy of the simulation results is dependent on the accuracy of the input data and the quality of the model. The bases of conducting the simulation should have knowledge and experience in the software and the structure he is simulating.
3.5 Data analysis
Data analysis of the load distribution in tied connections of reinforcement cages, when lifted from horizontal to vertical using LUSAS finite element software, involves evaluating the results of the simulation to identify any potential issues or problem areas. The following are some common steps for data analysis, The results of the simulation can be visualized in a variety of ways, including bar graphs, contour plots, and deformed shape plots (Abdrabbo and A., 2019). These visualizations can help to quickly identify any areas of high stress or displacement. The software provides detailed information on the stresses and displacements in the reinforcement cage. These values can be used to evaluate the safety and performance of the cage during lifting. The results of the simulation can be compared with the design values of the reinforcement cage. This will help to identify any areas where the design values are exceeded, indicating that the cage may be overloaded or underdesigned (Hack et al. 2020).
The load distribution in the tied connections is a crucial factor in the safety and performance of the reinforcement cage. The simulation results can be used to evaluate the load capacity of the connections and identify any areas where the connections may be failing or at risk of failure. Sensitivity analysis is also important to consider the uncertainty and the different factors that can affect the simulation results. Sensitivity analysis can be carried out to study how the results are affected by variations in the input data and the model (Cao and Gu, 2019).
It is important to note that the data analysis should be carried out by a qualified engineer with knowledge and experience in the software and the structure in question. The results of the simulation should be used in combination with other design tools.
3.6 Design Implementation
Design implementations of the load distribution in tied connections of reinforcement cages, using LUSAS finite element software, include, the first step is to create a 3D model of the reinforcement cage using the LUSAS software. The model should include all the relevant geometric details of the cage, such as the dimensions of the bars, the spacing between them, and the location of the tied connections. Next, loads and constraints need to be applied to the model. The loads would include the weight of the reinforcement cage and any external loads that may be present during lifting. The constraints would include the fixed points on the cage where it is supported during lifting.
The results of the simulation can be visualized in a variety of ways, including bar graphs. The bar graph will show the load distribution in the tied connections of the cage, which can be used to identify any potential problem areas.
3.7 Summary
The LUSAS software can also be used to evaluate the effect of different materials on the load distribution in the tied connections. This can help in selecting the best material for the reinforcement cage based on the results of the simulation. It is important to note that the implementation of the design using the LUSAS software should be carried out by a qualified engineer with knowledge and experience in the software and the structure in question. The results of the simulation should be used in combination with other design tools and engineering judgment to make informed decisions about the reinforcement cage.
Chapter 4: Data analysis
4.1 Introduction
In this chapter, an analysis of the various failure mode around an RC structure has been done with the help of finite element analysis. The entire study has been done with the help of building an RC structure model in LUSAS. In this regard, it can be said that through the help of building an RC structure simulation in the LUSAS software and finite element method analysis, an evaluation of the failure mode has been done.
4.2 Findings
Figure 4.1: Mesh of the beam
It can be seen that the above figure is suggesting on the reinforcement of the beam deck that needs to be constructed. It can be seen that. The cage geometry of the cage of the grillage has been done through the help of this process.
Figure 4.2: Grid of the cage
In this adobe figure, a grid section created for the RC cage delivery has been presented. It can be seen that this grid section has helped in terms of better design orientation.
Figure 4.3: RC grillage frame cage
The above figure is describing on the RC grillage frame cage that needs to be evaluated under the pretext of failure modes while lifting.
Figure 4.4: Lifting mechanism
It can be seen that the above figure is explaining on the lifting of the cage with the help of external forces. It can be said that the possible buckling of the cage is one of the major aspects that need to be considered as a critical point. “Axial buckling due to compression caused by inclined chains/strops” can be considered as failure mode during the lifting of the RC structure. Henceforth, through the help of this built LUSAS model, it is important to check whether there is a possibility of failure.
Figure 4.5: Lifting of the RC model
The above figure is suggesting on the vertical lifting of the model. On the other hand, through the help of lifting the model into the air, various failure mode analyses can be attributed.
Figure 4.6: Section
It can be seen from the above figure suggesting the sectional visualization of the RC structure. Therefore, through the help of implementing external lifting force on the RC cage structure, it is possible to evaluate some of the possible causes of the collapse.
Figure 4.7: Stress generated
This is the final evaluation of the model to which external stress implementation has been referred. It can be seen that upon implementation of the external stress, the above section of the RC structure has faced the majority of the stress (Weng et al. 2020). It is evident that stress on the upper section of the cage is suggesting that the first type of failure should be vertical buckling and needing of the structure. Under the pretext of observing maximum stress in the upper sectional reinforcement bars, it is possible to collapse under vertical bending and buckling.
On the other hand, from the above image, it is also evident that in-plane sway is another possible failure mode that this structure can face while lifting adobe the ground. It can be seen that the failure of vertical members happens due to in-plane sway type of failures. In case there is insufficient support above the top of the mat, there will be possibilities of in-plane sway. On the other hand, there is also the possibility of vertical discontinuity sliding as well as buckling of the reinforcement members (Salim and Sahib, 2022). The middle section of the cage structure is also suggesting that there is a high chance or possibility of out-of-plane bending as well as toppling. Therefore, it can be said from the above analysis that major four types of collapse can happen to an RC cage structure.
4.3 Evaluation
The collapse of a rebar cage depends significantly on the bracing and tie-ups efficiency. Loose bracing or inefficient spacing of the bars is the major cause of failure. It can be seen from the above analysis that the delivery of a better-reinforced cage model is significantly dependent on tie-up spacing and effective bracing (Fan et al. 2020). Splicing the cages is another factor that should be considered while lifting the cage.
Henceforth, it is evident from the above analysis that beam elements can eventually collapse due to the buckling of the upper bars. It was observed that the RC cage upper section witnessed most of the stress during the lifting of the element above the ground. Moreover, the deep beam elements can be laterally unstable as well (Parthasarathi et al. 2022). The usability of the cage is due to the insufficiency of support. The connection to the starter bars can be insufficiently robust that causing further instability in the structure. The ties between the starters can be another major area that can cause the failure of the RC cage. Henceforth, it can be said that, through the help of this LUSAS finite element analysis, it was observed that there can be multiple causes of failure within the RC cage structure
4.4 Summary
Henceforth, this section has analyzed whether RC structures can fail while being uplifted during construction. On the other hand, it was observed that there is various mode of failure that can happen to a reinforcement structure. It was observed that primarily, the structure can fail due to vertical buckling and bending of the structure. Similarly, the upper bars of the model have faced maximum stress thereby increasing the possibility of bending and toppling as well. It is important to mention that the in-plane sway of a structure can happen if the area is too high. Sliding and buckling of the structure is another possibility that can impact the structural stability of the element. Henceforth, this should be said that through the help of tie-up and bracing of the element, it is possible to avoid such failure.
Chapter 5: Discussion
5.1 Introduction
In a tied reinforcement cage, the load is distributed evenly among all of the ties that are connecting the bars. It is lifted from a horizontal to a vertical position, and the load distribution in the tied connections change which is already shown in the result section. This is because the weight of the cage is now being supported by vertical ties rather than horizontal ties. That’s why vertical links experience a more significant load than horizontal ties. On the other hand, the load distribution in the vertical ties may not be evenly distributed, as the weight of the cage may be concentrated at certain points. In this section, a discussion is performed which is based on the outcomes which come from the result of the LUSUS finite element software.
5.2 Model design
Using finite element software like LUSAS can be an effective way to model the load distribution in tied connections of reinforcement cages when the position of the cages is changed. The software can simulate the behavior of the reinforcement cage under different loading conditions, allowing engineers to analyze and optimize the design of the tied connections. The results from the model can be used to ensure that the reinforcement cage is stable and can support the loads it is designed for. Additionally, the model can be used to identify areas of the reinforcement cage where the load distribution is not optimal, and changes can be made to improve the design. Overall, using finite element software like LUSAS can be an important tool in the design and analysis of reinforcement cages and their tied connections.
At the first step of the design, a 3D model is required to create which is including the location of the tied connections. In this step, the units are set for the design of the reinforcement cage. The units are used for the measurement of the parameters of the cage. The file type needs to be set. For initiating the design of the reinforcement cage, the material properties are customized according to the needs (Kechavarzi et al. 2019). Then the loads are given as input and some conditions are required to make the boundary for the model such as load distribution for the reinforcement cage. After that, a nonlinear analysis is performed to evaluate the behavior of the reinforcement cage and the tied connections under the applied loads.
When the analysis is completed, then the result is required to review so that the stress and displacement distribution can measure in the case of the reinforcement cage and the tied connections. The results are then used to adjust the reinforcement cage design. It also becomes beneficial for the optimization of the load distribution in the tied connections. But always optimization is not required in the case of the design of the reinforcement cage (Hassanli et al. 2021). If the requirement is not met with the design of the reinforcement cage, is required to repeat the analysis until the design meets the required performance criteria. At the end of the design, the model is saved in storage. The saved model may be used for editing the design in the future.
5.3 Discussion of findings
After completing the analysis using LUSAS, it is important to carefully review the results to understand the behavior of the reinforcement cage and the tied connections under the applied loads. All the outcomes are discussed in this part of the discussion. The stress distribution is one of the important findings. The stress distribution in the reinforcement cage and the tied connections should be evaluated to ensure that they are within the allowable limits. High-stress concentrations should be identified and addressed. Excessive stress concentrations can lead to the failure of the reinforcement cage or the tied connections. Displacement distribution is the next outcome which should be evaluated to ensure that the reinforcement cage and the tied connections are not subjected to excessive deformation. Large displacements may indicate a need to increase the stiffness of the reinforcement cage or the tied connections (Rasheed and Ali, 2019).
Another one is load distribution. This type of distribution in the tied connections should be evaluated to ensure that they are properly distributing the loads to the surrounding structure. If the load distribution is not optimal, adjustments to the reinforcement cage or the tied connections may be necessary. Material properties are another main outcome. The reinforcement is highly dependent on the properties of the material. The behavior of the material of the reinforcement cage and the tied connections should be evaluated to ensure that it is consistent with the expected behavior. Any unexpected behavior should be investigated and addressed by showing the properties of the materials (Tullini and Minghini, 2020).
The safety factor for the reinforcement cage and the tied connections should be evaluated to ensure that they are providing an adequate margin of safety. If the safety factor is not adequate, adjustments to the reinforcement cage or the tied connections may be necessary. It is another outcome which is come from the analysis of the design of the model. All the discussed findings, from the LUSAS analysis, are very important. It ensures the reinforcement cage and the tied connections which are designed and constructed to meet the required performance criteria and provide an adequate margin of safety.
5.4 Summary
At the end of the discussion, it can be said that when the load distribution in tied connections of reinforcement cages is designed by using LUSAS software, one needs to create a 3D model of the reinforcement cage and surrounding structure, input the loads and boundary conditions, perform a nonlinear analysis, review the results, and use the results to adjust the design if necessary. In the area of the discussion of the findings, it is found that many key points outcomes. Among them the distribution of stress and displacement, the load distribution arises. Material behavior and safety factor are also very important and interpreted in the context of the specific design and performance of the project. The most important thing when the model is designed should be to ensure that the reinforcement cage and the tied connections are providing an adequate margin of safety.
Chapter 6: Conclusion and recommendations
6.1. Link with objectives
There is a fulfillment of the first objective because elements of safety are identified so that it can help in making the construction of principles of safety. Moreover, there is an application of an effective approach that can help in the determination of conditions. Procedures of safety are also implicated so that there are chances of development of implementations in this type of application. Therefore, all conditions are evaluated in this feature after analysis of conditions in this scenario. The second objective has been met because there is appropriate development of reasons for understanding the procedures of collapse. There is an evaluation of effective procedures and these are depicted as appropriate measures for making appropriate validation of approaches. Hence, these processes are contemplated after the execution of the entire procedure of research.
There is a fulfillment of the third objective because there has been the creation of models and these models can help in the abolition of vital issues. Hence, there has been a prevalence of procedures and these are implicated so that there are requirements for these strategies. There are chances of procedures and these procedures are taken into contemplation for evaluation of appropriate conditions. Hence, there are possibilities of procedures, and these are taken into contemplation for evaluation of causes of risks. There are recommendations for making an appropriate evaluation of approaches in this framework. Therefore, the fourth objective has been met after the derivation of pertinent approaches in this specified field.
Conclusion
After the loads and constraints are applied, the simulation can be run. The LUSAS software can be used to solve the equations of motion to determine the distribution of the loads throughout the cage during the lifting process. Based on the results of the simulation, adjustments to the design of the reinforcement cage can be made. This may include changes to the dimensions of the bars, the spacing between them, or the location of the tied connections. Once the design has been adjusted, the simulation can be run again to evaluate the new design. This process can be repeated until an optimal design is found that meets all the required safety and performance criteria.
6.2 Recommendation
The load distribution in tied connections of reinforcement cages, when lifted from horizontal to vertical using LUSAS finite element software recommends is for the tied connections, the load should be equally distributed among the ties (Chen and Pan, 2021). The ties should be placed at equal intervals around the circumference of the cage. The ties should be placed at a minimum of one-third of the cage’s circumference from each other. The ties should be placed in the same plane as the longitudinal reinforcement bars.
The ties should be placed in such a way that all of the vertical bars are held in tension when the cage is lifted. The ties should be placed such that the cage is held in equilibrium during lifting. The ties should be designed to withstand the lifting force, taking into consideration the forces induced by the deformations of the cage. The forces induced by the deformations should be balanced with the forces induced by the ties. The ties should be sized to suit the strength requirements of the cage. If applicable, the ties should be designed to allow for deformations of the cage due to the lifting process.
Recommendation 1: Implementation of measures of safety for the depiction of “reinforcement cages”
There is a requirement to evaluate conditions so that it can help in the evaluation of procedures of safety. There are chances of effective measurement of protocols that it can help in the appropriate derivation of conditions (Chen and Pan, 2021). Hence, these are termed effective measures for the derivation of respective suggestions in this field. Standards are relevant so that there are chances of delivery in this particular category.
Recommendation 2: Stability is required in the establishment of appropriate fields of connection
This concentration of load on the bottom ties can lead to potential failure if the ties are not strong enough to support the weight of the cage. Therefore, it is important to properly design and engineer the ties and reinforcement cage to ensure they can withstand the load distribution during the lifting process. Additionally, as the reinforcement cage is lifted from the horizontal to the vertical position, the forces acting on the ties also change. In the horizontal position, the ties are primarily under tension forces due to the weight of the cage being evenly distributed.
6.3 Future Scope
The bases on the above discussion, there are many technical perspectives that can be represented in the future based on the modification. The load distribution in tied connections of reinforcement cages, when lifted from horizontal to vertical using LUSAS finite element future scope, is to calculate the load distribution in the reinforcement cages. LUSAS finite element provides a powerful tool for the analysis and design of reinforced concrete structures and can be used to determine the load distribution in the reinforcement cages.
It allows the user to define the geometry, material properties, and boundary conditions of the structure, and then simulate the behavior of the structure under various loading conditions. The results obtained from the analysis can be used to assess the safety of the structure, and to optimize the design parameters. Additionally, the software can be used to evaluate the performance of the reinforcement cages under different loading conditions and to identify areas of potential failure or weak spots in the reinforcement. However, as the cage is lifted, the ties at the bottom of the cage experience both tension and compression forces due to the weight of the cage being concentrated on them. The ties at the top of the cage continue to primarily experience tension forces. Furthermore, when the reinforcement cage is lifted, the ties will also experience bending moments. These bending moments are caused by the weight of the cage being off-center from the geometric center of the cage. A proper analysis of the forces and stresses on the ties during lifting can ensure the safety and stability of the reinforcement cage.
