摘　　要：讨论了在不确定条件下的结构鲁棒设计问题.基本思想是在设计阶段保证质量,降低结构的失效概率.通过正确选择设计变量,使响应对不确定变量的敏感性最小来达到结构鲁棒性.理论和计算表明,当响应与不确定量为线性关系时。The problem of designing structures under uncertainty was considered. The basic idea was to ensure quality at the design stage by minimizing sensitivity of the response to uncertain variables by proper selection of the design variables. It proves that when the response in linear with the uncertain variable, the reduction in sensitivity implies less probability of failure.

关 键 词：结构力学 敏感性 鲁棒设计 优化设计
