Shape optimization of free-form grid structures based on the sensitivity hybrid multi-objective evolutionary algorithm

In this paper, a novel shape optimization method is proposed to improve the mechanical performance of the free-form grid structures while satisfying the architectural requirements. The height of control points are considered as the optimization variables, the structural strain energy and the compreh...
