Abstract

This paper discusses the development of a reliability-based multi-objective design tool for solving structural optimization problems. The developed design optimization tool has the capability to take into account the effects of variability on the proposed design through a user specified reliability design criterion. The nonlinear goal programming method used, provides for a design method that eliminates the difficulty of having to define an objective function and constraints, while at the same time has the capability of handling rank ordered design objectives or goals. In this work, multiple design criteria including structural weight, load induced stress, deflection, and mechanical reliability are considered. For simulation
