| 摘 要： | 以汶川地震震中附近的一栋典型RC框架结构为背景,采用BRB支撑加固来增强其抗震能力,并采用基于动力增量分析(IDA)的地震倒塌易损性分析方法,对加固后的抗倒塌能力及其影响参数进行了分析。结果显示,以结构抗倒塌能力为目标,BRB支撑方案的加固效果要好于普通支撑加固方案,相同参数情况下,A形支撑布置方案的加固效果好于X形支撑布置方案。

| Abstract: | This paper is based on a typical RC frame that was closed to the epicenter and collapsed during the Wenchuan earthquake.The seismic collapse resistance of the frame was strengthened by BRB brace.Collapse fragility analysis based on incremental dynamic analysis is implemented for each strengthening scheme to compare their effects and to analyze the influence of critical parameters.The results show that the BRB brace performs better than the conventional brace.With the same strengthening parameters,the A-shap... |
