低周反复水平荷载作用下分体柱承载力的试验研究

Experimental Study on Bearing Capacity of Separated Columns Under Horizontal Cyclic Loading

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，在已有分体柱抗震性能及刚度分析的基础上，导出了分体柱的承载力计算模型及实用计算公式，提出了分体柱极限承载力的设计计算方法。

Based upon the experimental study on six separated columns with high axial compression ratiounder horizontal cyclic loading and the analysis on the seismic behavior of the separated columns,this paper has established the model and practical formulas for the calculation of their ultimatestrengths. Finally, the design and calculation method of the strength of such columns are presented.
