摘　　要：采用赵国藩提出的近似计算方法计算结构的系统失效概率,并推导了相应的敏度计算公式,由此进行基于可靠性的鲁棒设计.计算实例证明,基于可靠性的鲁棒设计对提高结构的可靠性非常有效,而且在生命周期内。The structure fail probability was calculated with an approximate computation method proposed by Zhao Guofan and the relative derivative calculation formula was derived. The example shows that the robust design based on reliability is very effective to improve structures reliability index, and the designed structures have stable reliability index and quality in the life cycle of structures.

关 键 词：结构力学 鲁棒设计 可靠性
