摘　　要：针对钢筋混凝土建筑结构展开了抗震性能研究,提出一种高适应性的Pushover分析方法.在传统Pushover方法基础上,充分考虑高阶振型和结构刚度蜕变的影响,通过补充设计提升抗震性能分析的适应性.为了有效应对地震中的不确定性,配置了3种载荷.实验结果表明:对于钢筋混凝土结构,在倒三角载荷、抛物线载荷及分层分布载荷下,可以从位移、角位移方面给出稳定的抗震性能分析.The high adaptable Pushover analysis method is proposed to study the seismic behavior of rein-forced concrete structures. This method is based on the traditional Pushover method, considering the effect of stiffness degradation and high order vibration modes？ the seismic performance analysis of adaptability is im-proved by additional design. In order to effectively deal with the uncertainty in the earthquake, three kinds of load are distributed. The experimental results show that the seismic behavior of reinforced concrete structures can be analyzed according to the displacement and angular displacement under the inverted triangular load, the parabolic load and the stratified distribution load.
