Abstract :
For reliability-based topology optimization (RBTO) of double layer grids, a two-stage
optimization method is presented by applying “Solid Isotropic Material with Penalization”
and “Ant Colony Optimization” (SIMP-ACO method). To achieve this aim, first, the
structural stiffness is maximized using SIMP. Then, the characteristics of the obtained
topology are used to enhance ACO through six modifications. As numerical examples,
reliability-based topology designs of typical double layer grids are obtained by ACO and
SIMP-ACO methods. Their numerical results reveal the effectiveness of the proposed SIMPACO
method for the RBTO of double layer grids.
