| 摘 要： | 结构抗震可靠性的分析一般即采用动力可靠度的研究方法进行。本文提出了进行结构抗震可靠度分析与计算的一种新方法,即基于破坏指标界限值的结构抗震可靠度分析方法。该方法在标定结构破坏指标范围进行破坏等级划分的基础上,采用JC法对结构在不同烈度地震作用下的各破坏状态概率进行计算,从而完成对结构抗震可靠性的分析。计算实例表明,该方法与经典动力可靠性分析所得结论相一致,这表明了本文方法的正确与可靠。

| Abstract: | In general,the seismic reliability of structure is analysed by the method of dynamic reliability.In this paper,a new analytical method of structure seismic reliability is proposed,which is the analytical method of structure seismic reliability based on boundary value of damage index.In the new method,on the base of the division of damage state according to the range of damage index,each damage state probability under the action of earthquakes with different intensities is calculated by the JC method,so that... |
