This work presents an approach for the structural optimization of 2D and 3D aerospace truss structures. The main goal is to reduce the volume (or weight) of the structure while satisfying constraints such as compliance, member stresses, local or global buckling, for one or more load cases. Starting from an initial ground structure built from an optimal connectivity between all points, the best topology is determined, using a Sequential Linear Programming (SLP) algorithm. The design variables are the cross sectional areas of the bars, to be chosen within a specified range (maximum and minimum possible values).Studies of this nature have great importance in the task of developing lighter structures, without jeopardizing its functionality.
