Abstract
This report describes an expandable software system for optimization-based, interactive computer-aided design of structures. This system can be used for the design of statically and/or dynamically loaded structures which exhibit linear or nonlinear response. The software is the union of an interactive base code for the management of the computer-aided design process named DELIGHT, a dynamic nonlinear general-purpose structural analysis package named ANSR, a library of optimization algorithms specialized for the type of mathematical programming problems characteristic of structural design, and 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 problem to the system by supplying a minimal amount of software or by selecting software from expandable libraries.
