Abstract

The optimized shape of trusses are found by presenting a new selection and reproduction operator. The stress, buckling an displacement constraints, consistent with design code, are used. Design variables are discrete size variables (member areas) and continuous shape variables (nodal coardinates). The proposed methods, is fast and has a stable convergence. In addition, it results in an optimized structure with low weight.
