Abstract

This project deals with optimization of a steel space truss. Optimization is a process of subjecting all members present in the structure to its maximum usage thereby ensuring the utilization ratio of each and every element to be above 80%. It is to be noted that the structural properties should not be compromised. The structure has to be made of limit state design and should be a simply supported roof. Optimization of such a truss has been made possible by two approaches for varying the sections of the truss. Based on the analysis made on the results obtained from these trials, the optimal solution of the model is arrived. This report briefly explains the approaches, procedure and result analysis of the space truss optimization process. By using steel structure we can speed up the project, increase the scrap value, reduce foundation block cost and increase the column free working space. Optimizing a steel structure can make the steel structure more efficient and economical.
