| 摘 要： | 考虑结构不同功能失效时损失情况不同这一事实，遵循抗震设计规范的“小震不坏，中震可修，大震不倒”的抗震设计原则，提出了基于不同功能要求的可靠度优化设计方法，计算结果表明，采用此方法可以在概念意义上合理改善结构体系的抗震性能，降低结构在地震作用下的损失。

| Abstract: | The different types of failure could induce different structure damage. A principle for structure design against earthquake has been received, that is, structure should be un-damaged under minor earthquake, repairable under moderate earthquake and un-collapsed under large earthquake. On the background of design principle, this paper presented an optimum design method based on the demand of different functions and reliability analysis. Through a numerical example, it is shown that with the help of the method, the aseismic capability of structural system can be improved and its failure loss under earthquake reduced. |
