Optimization of Steel Trusses Using Genetic Algorithm

The use of optimization process is a much-needed step in the field of construction today. But optimization is not being used very efficiently in structural engineering. Weight optimization is one of the structural optimization processes which optimizes the weight of the material used in the construction. The process provides an optimum area of cross-section for the steel sections. By optimizing the weight, the material cost has been reduced. It helps in improving the economic sustainability. The paper presents a study of optimization of trusses using genetic algorithm. The trusses considered for optimization are a two-bar truss, a three-bar truss and a ten-bar truss. The software used for this process is MATLAB2013a. The results are cross-checked using STAAD. Pro and manual calculations
