Abstract

This paper presents a constant-weight fully-stressed topological design method that can attain a final structural configuration with less reanalysis iterations. Hinton and Sienz proposed a simple algorithm by which a fully-stressed light-weight structure can be obtained by an iterative mass removing process, and thereby a time-consuming topological optimization procedure can be avoided. The new approach proposed in this study can further increase the computational efficiency and meanwhile create compatible final designs. This constant-weight fully stressed approach provides a unique strength of maintaining the structure at a predetermined weight level during the course of seeking the best topology. Two fully-stressed methods are compared in two illustrative problems including a cantilever beam and a bridge.
