摘要: 对Z形截面柱进行抗剪承载力试验，通过分析试验过程中构件裂缝的开展、破坏的形态等试验现象，探索了Z形截面柱受剪破坏机理及受剪破坏规律，得到了轴压比、剪跨比、配箍率以及肢高厚比等因子对试件延性性能和抗剪承载力影响规律，并在试验结果的基础上，给出Z形截面柱抗剪承载力回归公式和可用于工程设计使用的抗剪承载力计算公式，并给出若干工程设计建议，供设计人员参考。

Abstract: The shear carrying capacity experiment of Z-shaped column was carried out,through the synthetic analysis of both crack expanding condition and failure modes,the shear failure mechanism and shear failure law were studied,it was obfained the effect of the factors,such as axial compression ratio,shear span ratio,stirrup reinforcement ratio and ratio of section height to section thickness of column 1eg,which affected the shear carrying capacity and ductility capacity of Z-shaped column.And based on the results of the experiment,the regression formula,the formula for the structure design and some suggestions on design of practical projects were presented,which provided a reference for structure designer.
