This report describes an expandable software system for optimization-based, interactive computer-aided design of structures. This system can be used in the design of statically or dynamically loaded structures which exhibit linear or nonlinear response. The software is a combination of: (1) an interactive base code for the management of a computer-aided design process, DELIGHT, (2) a dynamic nonlinear general-purpose structural analysis package named ANSR, (3) a library of optimization algorithms specialized for the type of mathematical programming problems characterizing structural design, and (4) specialized software for the design of seismic-resistant planar steel frames. Flexibility has been emphasized in the development of this system so that a wide range of structural problems can be considered. The user describes his particular problem to the system by supplying a minimal amount of software or by selecting software from expandable libraries.
