Abstract
Topology optimization of two dimensional structures subject to dead and wind loading is considered. The wind loading is introduced into the formulation by using standard expressions for the drag force. A design problem formulation is constructed for minimum compliance design subject to a volume constraint and using the popular SIMP material model. The method of moving asymptotes (MMA) is used to solve the optimization problem. The MMA is modified by including line search and changing the formula for the update of asymptotes. In order to obtain black/white design, intermediate density values, which are used as design variables, are controlled by imposing an explicit constraint. Numerical examples demonstrate that the proposed formulation is successful in incorporating the effect of wind loading into the topology optimization problem.
