Structural Design Optimization Status and Direction

Abstract

This paper discusses the use of optimization techniques for structural design. This discussion begins with a brief historical review of this technology from the initial concept to modern approximation techniques. The present state of the art is reviewed and some examples are offered to demonstrate the state of the art. Finally, future needs are addressed to indicate some of the challenges that lie ahead. It is concluded that the state of the art is now reasonably well refined. The challenge now is to assimilate this technology into the practicing design environment.
