Applications of finite element method in structural engineering

Abstract

It is a challenge for structural engineers to analyze complicated structural forms effectively using conventional analytical methods. Therefore, structural engineers prefer to use a commercial finite element software rather than using analytical methods. Many finite element software are based on the displacement based finite element method. As it is an approximate method, many drawbacks have been identified in applications in structural engineering due to misconceptions of users. Therefore, the objective of this study is to identify the limitations of using different finite elements to model structural components in buildings such as trusses, beams, slabs, foundations and their connections. To achieve the above objective, several case studies are selected and analysed using SAP2000 software. Based on the results, proper guidelines have been proposed for structural modelling. It is important to note that this study was limited to materials in linearly elastic behaviour.
