［摘要］对当前剪力墙轴压比的计算方法进行了讨论，指出了目前规范关于剪力墙轴压比计算方法中存在的一些问题。介绍了剪力墙轴向内力的分布特点，提出了剪力墙在重力荷载代表值和水平地震作用下“分段轴压比”的计算方法，给出了剪力墙轴压比限值建议，并通过工程案例说明了方法的应用。结果表明此方法更加合理，更有利于充分发挥剪力墙的抗震潜能。

Abstract:The calculation method of shear wall axial compression ratio was discussed, and some problems in calculation method of shear wall axial compression ratio according to current code were pointed out. The distribution characteristics of axial internal forces of shear wall were introduced,  the calculation method of “sectional axial compression ratio” under gravity load representation and horizontal earthquakes was put forward, and the suggestion of the shear wall axial compression ratio limit was given. An engineering example was offered to explain the application of the method. The results show that this method is more reasonable, and is more conducive to giving full play to the seismic potential of shear walls.

Keywords:shear wall axial compression ratio; calculation method; sectional axial compression ratio; compression ratio limit
