摘　　要：进行了四个高含钢率钢骨混凝土柱的拟静力试验,试验结果表明其抗震性能接近钢结构构件:具有承载力高、延性大、滞回曲线饱满等特点。在此基础上,分析了此种结构的滞回特征,构建了基于水平力和侧移关系的高含钢率钢骨混凝土柱的恢复力模型,给出了参数确定方法。与试验曲线进行对比,两者形态接近,关键参数吻合良好。Four SRC columns with high rate of encased steel（HS-SRC）were tested under cyclic loads.The test results show that the HS-SRC columns demonstrate good seismic performance as pure steel members,such as high capacity,large ductility,and remarkable ability of energy consumption.Based on the experimental study,the paper analyzes the hysteretic property,then a simple restoring force model of HS-SRC columns is built.The method for calculating the key parameters of model is introduced.By comparison between the model and the test curves,it is realized that the main hysteretic performance may be well simulated by the model.
