Structural optimization of composite structures using an energy method

Abstract

The potential of structural optimization in the design of structures is growing rapidly with the advancement of the computer technology. In this paper, a formulation of structural optimization problem using an energy method is presented, for which solution a nested bilevel optimization is utilized. The method is applied on two practical examples, namely a nonlinear sizing problem for a two span girder and a discrete shape optimization of a truss bridge. These demonstrate the applicability of the method.
