基于随机化Pushover的结构整体抗震可靠度参数分析
Parameter Analysis of Structural Global Seismic Reliability Based on Randomized Pushover Method
摘要
Abstract
To investigate the applicability of relevant parameters in the process of global seismic reliability calculation of reinforced concrete (RC) frame structures by means of randomized Pushover method,a structural global seismic reliability program based on randomized Pushover method was compiled by calling SAP2000 using Matlab.An eleven-story RC frame structure was established to calculate the distribution of maximum story drift angel and the global failure probability using the program.The calculated results were compared with statistical results of the time-history analysis under a large sample of real seismic waves.The comparison shows that the distribution of the maximum story drift angel and the structural global failure probability obtained using the two methods were significantly different.Based on this,a correction method was proposed to greatly reduce the differences and an example was given to verify the applicability of this method.关键词
