中文摘要：
将可靠性设计理论和稳健设计方法相结合，讨论不完全概率信息的梁结构可靠性稳健设计问题，提出可靠性稳健设计的计算方法。把可靠性灵敏度溶入可靠性优化设计模型之中，将可靠性稳健设计归结为满足可靠性要求的多目标优化问题。在基本随机参数的前四阶矩已知的情况下，通过计算机程序可以实现不完全概率信息的梁结构可靠性稳健设计，迅速准确地得到不完全概率信息的梁结构可靠性稳健设计信息。
英文摘要：
Based on the rehability design theory and the robust design method, the reliability-based robust design of beam structure under incomplete probability information is extensively discussed and a numerical method for reliability-based robust design is proposed. The reliability sensitivity is added to the reliability-based optimization design model and the reliability-based robust design is described as a multi-objection optimization. On the condition of known first four moments of basic random variables, the respective program can be used to obtain the reliability-based robust design information of beam structure under incomplete probability information accurately and quickly.
