摘要
在荷载、环境和材料内部因素的作用下,结构的性能会逐步劣化。结构性能的劣化使得结构的实际可靠度比预设计的可靠度低。本文论述了结构性能劣化的原因,提出考虑抗力变化的结构可靠度的分析方法。本研究提出的方法简便易行,且形式上能够与现有的结构可靠度分析方法相协调,因而可以作为劣化结构可靠度分析的参考方法。
Under the action of loading,environments and interior factors of materials, the performance of structures will deteriorate gradually with the actual reliability of structures lower than the design reliability. In this paper, the causes of structural performance deterioration are discussed and an analysis method for deteriorating structures is presented. This method is simple and in conform ity with the current structural reliability method It can be used as a basic method for reliability analysis of deteriorating structures
