摘要
为更准确反映重庆历史文化建筑在刚度和承载力分布不均匀时的抗震能力,该文在楼层综合抗震能力指数计算中引入延性指标,采用该方法计算特定框架结构得到的楼层综合抗震能力指数与规范方法较为接近。
In order to reflect more accurately the seismic capacity of the historical and cultural buildings in Chongqing with unevenly distributed stiffness and bearing capacity, this paper introduces ductility index to the calculation of the comprehensive seismic capacity index of the storey, which is turned out to be quite close to the one calculated with the normative approach when used for particular frame structures.
