An integrated system for optimal structural synthesis and remodelling

Abstract The paper presents an integrated system approach to efficient structural synthesis. It is based on a production analysis program (EAL), two general purpose optimization programs (CONMIN and NEWSUMT) and several problem-independent processors (some available with PARS and a few recently developed on EAL). The approach makes it possible to resize structures which can be “generically” modelled. The paper describes the advantages of following this integrated approach, the process of incorporating PARS (Programs for Analysis and Resizing of Structures) into EAL (Engineering Analysis Language) to form EAL/PARS and some of its newly added capabilities. An advanced synthesis system with enhanced generality and flexibility is achieved by taking advantage of the EAL higher order language commands and data base. The EAL modular structure and the ease with which new processors can be added to EAL make this system potentially adaptable to a wide spectrum of structural optimization problems.
