恶劣环境下结构可靠度的一种分析法
Reliability Analysis of Structures in Adverse Environment
摘要
Abstract
Structural resistance changes greatly with time in adverse environment (for example, chemical environment). The minimum resis-tance method is presented for reliability analysis of structures considering resistance change with time and is compared with the method givenby the current building codes and the equal resistance method. The feature of the three methods is analyzed. The idea that the minimum re-sistance time can be taken as a key point for structural reliability analysis is presented. The minimum resistance method is simple in calcula-tion, intuitive in concept and compatible with the current building codes. It can be a reference when analyzing reliability of structures in ad-verse environment.关键词
