Abstract : Recent extensions to ACCESS-3 computer program for structural synthesis are described herein. The original program was limited to the optimization of relatively small problems having truss, membrane and shear panel elements. The new extensions include: restructuring of the program to allow efficient out-of-core solution of the large matrices encountered during analysis, approximate problem generation and gradient evaluation, increasing the number of degrees-of-freedom per node from 3 to 6, and adding a triangular plate element which admits combined membrane and bending behavior.
