摘要：

Recently, Goh and Wang (1989) presented a unified approach for solving cross-section structural optimization problems under general constraints. In a continual development of the above unified approach, two important extensions have been made to enhance its versatility. They allow the optimization of variable piecewise segmental lengths and/or variable interior point constraint positions. This sequel paper shows how these extensions are incorporated in the unified approach and presents the derivation of gradient expressions (required in the optimization routine) of the objective functional and constraints with respect to these new variables. Some illustrative examples are solved to demonstrate the new features in the approach. Furthermore, a recent refinement in handling continuous state constraints is presented.
