摘要
根据已有楼梯抗震试验结果,给出梯段板抗震性能水平及其量化指标;建立框架结构层间位移角与梯段板抗震性能指标之间的关系,并进行楼梯抗震性能宏观评价;基于梯段板、梯柱、与休息平台直接相连的框架柱等楼梯构件,给出既有RC框架结构板式楼梯抗震性能评估的具体方法和步骤.
Based upon the seismic performance test results of the staircases, this paper managed to determine the seismic performance levels and quantitative indicators of plate stairs, set up the relationship between the interlayer displacement angle of frame structures and seismic performance indicators of plate stairs, and conduct the macroscopic evaluation of seismic behavior of stairs in according with the framework performance level specified by the code. A method and process of evalua- ting the seismic the seismic performance of the existing stairs of the RC frame structure were also pro- posed on account of the performance of components, i.e. stair plates, staircase columns, the structural columns connected with rest platform, and etc.
