TRUSS STRUCTURAL SHAPEOPTIMIZATION BASED ON THEEXPERIMENTAL DESIGN METHOD

This study is concerned with shape op- timization of three truss structures, which is a setof truss structures of layout design problem. Toan optimal problem with a large number of de-sign variables, the conventional structural optimiza-tion method using mathematical programming isnot very efficient. In this study, the effectiveness ofthe optimal programming based on the experimental design method is demonstrated: and the shapeoptimal results show some rational consistency.
