抗震结构“小震不坏,大震不倒”可靠性分析

THE RELIABILITY ANALYSIS OF SEISMIC-RESISTANT STRUCTURE BASED ON SEISMIC CODE OF CHINA

摘要: 为检验结构在设计基准期内是否满足“小震不坏、大震不倒”的设计原则,本文在定义了设计基准期内“小震”烈度和“大震”烈度的基准上,求出了结构在弹性范围内其承载能力的可靠性及在非线性状态下基于最大变形破坏机制下结构不发生倒塌的可靠性,分别作为结构在设计基准期内完成“小震不坏”、“大震不倒”预定功能的概率。

Abstract: In order to check whether design be met or not for a structure during its design life, this paper has derived the formula of structural reliability in elastic range as well as in nonlinear range based on defintion of small earthquake intensity and great one given in the paper.
