| 摘 要： | 本文给出了可用于实际工程结构优化设计的特征应力约束和相应的安全度目标及有关算例.采用本特征应力约束可成功地用一个约束代替数量很大的各构件强度与稳定性约束,给优化计算带来很大方便.相应的安全度目标可解决一般工程技术人员希望自己设计的结构宁愿较重也要安全不易破坏的心理要求,使结构优化更能适应工程实际.

| Abstract: | This paper proposed conceptions and computations about the constraint to characteristic stress and the sefety degree objective used in optimum design of engineering structures. With the constraint to characteristic stress of structures, a vast amount of stress constraints of members can be replaced by one constraint conveniently. In designing structures, many engineers prefer that they are heavier, but must be safer. This intention can be satisfied with the safety degree objective. Related examples are given in this paper. |
