Optimal truss sizing by modified Rao algorithm combined with feasible boundary search method

作者:

Highlights:

• An efficient constrained Rao algorithm is established for continuous truss sizing.

• The method, named FBSmRao, always provides fully feasible design.

• FBSmRao is simple and requires no algorithm-specific control parameter to perform.

• FBSmRao successfully optimizes four benchmark trusses with static constraints.

• The optimized designs are competitive in terms of quality and robustness.
