MATERIAL BEHAVIOR AND OPTIMUM DESIGN OF STRUCTURAL SYSTEMS

This study addresses the need for a general constitutive relation for material behavior, and for quantifying redundancy of an optimized design for truss systems. A general constitutive model based on seven parameters along with the scant stiffness method and Rosenbrock's minimization algorithm are presented. The concepts of reserve and residual strength are used to study the effect of optimization on system strength and redundancy. Stress and displacement behavioral constraints are considered both separately and simultaneaously to investigate their influence on the optimum solution for brittle and ductile truss systems. The findings of the study are discussed.
