Abstract
Structural Topology and Shape Annealing (STSA), as a heuristic mathematic algorithm, achieves the real topology optimization of truss structures but little considering the mechanical characters of structure. Fully stressed design (FSD) criteria, as a mechanical method, is good at sizing optimization of the fixed configuration structures. The paper aims to apply the mechanical algorithm to guide the heuristic search process of STSA and establish a new hybrid algorithm for the truss optimization. The way integrating STSA with FSD are investigated basing on the study of the topology optimization of planar truss. The results indicate that the novel algorithm is meaningful and better than the solo shape annealing algorithm for the topology optimization of truss structure subjected to stress constraint and Euler buckling constraint.
