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。
In this paper, based on the experimental study of six columns with high axial compression ratio and low cyclic repeated horizontal loads, based on the analysis of seismic performance and stiffness of existing split columns, the bearing capacity calculation model for split columns is derived and applied. Based on the calculation formula, a design calculation method for the ultimate bearing capacity of split columns was proposed.
