Abstract or Table of Contents
Knowledge-based systems for structural design developed to date have used simple geometric representations which have not provided adequate spatial reasoning. Shape grammars are suggested as a representation for a knowledge-based system capable of performing spatial and functional reasoning. The representation needs to serve all disciplines involved in the design process, where different semantics of each discipline are associated with the same spatial information about design objects. The representation is demonstrated in the building design environment, where possible structural systems can be generated dependent upon the building's spatial layout.
