Abstract

In this paper, a novel non-linear shape optimization method is presented. In a first step, ten different prototype CFS sections are optimized for maximum flexural strength based on EC 3. All EC 3 requirements, as well as specific manufacturing and construction con-straints, are taken into account in the optimisation process. Global optimal solutions are obtained through the Particle Swarm Optimisation (PSO) algorithm. Subsequently, the PSO algorithm is linked to an inelastic post-buckling analysis using ABAQUS and an optimisation is carried out towards maximum energy dissipation. It is shown that, for the same amount of material, both bending capacity and dissipated energy can be significantly increased.
