Structural Optimization of Truss Using Finite Element Analysis

Trusses are most commonly used structure in industrial buildings, warehouses, bridges, transmission tower etc. There are different types of trusses available for construction. The analysis and design of an economical and stable truss system for utilization in industrial buildings., storage rooms., bridges., warehouses., transmission towers etc. is necessary. The present study is done on static analysis and optimization of truss system to get optimal and economical configuration of truss. Total cost of the structure depends upon mass of the structure and mass is directly relative to the material consumed by the skeleton of the structure. This paper presents the use of programming language MATLAB for static analysis of truss structure using 'Finite Element Method' and the `Topology Optimization' will be done based on the energy stored in the member. Static analysis of a 13 bar benchmark truss is done using MATLAB programming code and various results have been obtained. After interpretation of these results the safest and most economical system will be decided. The study has been extended to space truss for static analysis of transmission tower for different loading conditions.
