ABSTRACT

In civil engineering, the sizing optimization of truss structures is a widely used practice. The aim of the optimization is to minimize the total weight of truss members by considering the constraints of several members and nodes. Two types of constraints are important in design and these constraints are stress and displacement limitations. In the recent study, a non-linear programming tool employing the interior-point algorithm was integrated with the analyses of truss structures. As numerical examples, two space structures and a plane structure were optimized. The results were compared with the documented methods. As a conclusion the proposed method is more effective on computation time compared to other methods.
