Synthesis of Initial Form for Structural Shape Optimization

Abstract

Techniques that use qualitative reasoning for structural configuration synthesis and form design are critically examined. Both algorithmic and heuristic methods are considered. Because of the limitations of these methods a hybrid approach is presented. A shape algebra is developed for structural synthesis which leads to a systematic method for generating structural arrangements. This algebra raises the possibility of transforming structural synthesis into a science instead of the art that it currently is. The method is well-suited to automation exploiting a computer’s capability to manipulate symbols. The method searches for good candidate structures that can be used as the initial form for numerical programs for shape and size optimization.
