地震作用下钢筋混凝土柱的可靠度分析
|
摘要
根据我国现行规范抗震设计的基本原则,基于现行规范DL/T 5057-1996的规定,建立了钢筋混凝土柱在地震作用下的承载力极限状态方程,根据给定烈度下地震作用的概率分布类型,以各种设计参数作为基本变量,采用Monte-Carlo模拟法,对不同偏心距和不同荷载效应比值下,钢筋混凝土柱受压和受剪承载力的抗震可靠度进行了计算分析,结果可供现行规范修订时参考.
According to the fundamental principles of aseismic design in present code,the ultimate state equations of reinforced concrete columns based on the relative provisions of present code DL/T 5057-1996,subjected to earthquake were built up.In terms of probability distribution at given seismic intensity,regarding the design parameters as the basic variables,the aseismic reliabilities of compression and shear for reinforced concrete columns in different eccentricity and in different load effective ratios have been analyzed by using the method combined Monte carlo simulation.The results can be referenced in revising the present code.
