摘要:
以汶川地震震中附近的一栋典型RC框架结构为背景,分别采用普通支撑、防屈曲支撑(BRB)和粘滞阻尼器支撑3种加固方案来提高其抗震能力,并采用基于动力增量分析(IDA)的地震倒塌易损性分析方法,对各种加固方案的抗倒塌能力及其影响参数进行了分析。结果表明:以结构抗倒塌能力为目标,粘滞阻尼器支撑加固方案的效果优于BRB加固方案,而BRB方案的加固效果要优于普通支撑加固方案; 相同参数情况下,A型支撑布置方案的加固效果优于X型支撑加固。
Abstract:
Taking a typical reinforced concrete(RC)frame structure that was close to the epicenter during the Wenchuan Earthquake as background, the seismic collapse resistance of the frame was strengthened by attached substructures, including conventional brace, buckling-restrained brace(BRB)and viscous damper brace. Seismic collapse fragility analysis method based on incremental dynamic analysis(IDA)was implemented for each strengthening scheme to compare their effects and to analyze the influence of critical parameters. The results show that the viscous damper brace strengthening scheme performs better than the BRB, and the BRB performs better than conventional brace. With the same strengthening parameters, the strengthening effect of A-shaped bracing scheme is better than that of the X-shaped scheme.
