Abstract: Optimization of any truss structure is an important research topic due to the complexity of problems and the benefits to industry. It is an essential need for any industrial manufacturer to optimize their design with respect to apparently conflicting technical and financial goals. To achieve the optimized design, many methods are proposed and tested by researchers for a long time. The most popular method is to integrate GA and FEA to run the simulation. MATLAB being a powerful mathematical tool can run Genetic Algorithm (GA), which is an efficient method to optimize complex problems very effectively. ANSYS on the other hand is an efficient finite element analysis (FEA) tool used to analyze variety of problems - including structural problems. Therefore, in this paper we have used the same method to optimize a 40-bar truss structure. In order to minimize the weight, the volume is minimized under the constraints of maximum stress and maximum deflection.
