摘　　要：本文通过六根分体柱在高轴压比和低周反复水平荷载作用下的试验研究,分析了轴压比、配箍率等对分体柱的刚度、裂缝、最大承载能力、破坏形态及其滞回特性等抗震性能的影响;分析了过渡区设置和斜向水平荷载对分体柱受力性能的影响。提出了分体柱的刚度计算方法。Based on the experimental study on six separated columns with high axial compression ratio and under horizontal cyclic loading, this paper analyzes the effects of axial compression ratio and stirrup reinforcement ratio on the seismic behavior of the separated columns, including rigidity, cracking, maximum bearing capacity, failure features and hysteresis curve etc. It also analyzes the influences of the setting of the transition region and the inclined horizontal loading on the mechanic property of the separated columns. Finally, the practical formulas for calculating the stiffness of such columns are presented.
