Structural Analysis Using Finite Element Method
Abstract
Structural Analysis Using Finite Element Method is a challenge for structural engineers to effectively analyze complicated structural forms using conventional analytical methods. Structural engineers therefore prefer to use software for commercial finite elements rather than analytical methods.
Many software for finite elements are based on the method for displacing finite elements. Since it is an approximate method, many drawbacks have been identified in structural engineering applications due to user misconceptions.
The objective of this study is therefore to identify the limitations of using different finite elements to model structural components in buildings such as trusses, beams, slabs, foundations and their connections.
Several case studies are selected and analyzed using SAP2000 software to achieve the above objective. Proper guidelines for structural modeling were proposed based on the results. It is important to note that this study was limited to materials in linear elastic behaviour.
Conclusion
At PZT patches, translational displacements were obtained in the direction of applied forces at an interval of 1 kHz. Electrical admission was obtained at an interval of 1 kHz. The conductance signature for the PZT patch was drawn and compared to the experimental signature.
The patterns of both signatures were observed in the same way. Both signatures at the same frequencies obtained peak conductance. But there is a magnitude variation. These variations are due to high frequency analysis, boundary effects and concrete damping uncertainty.
