摘　　要：带端柱高性能混凝土剪力墙构件具有良好的抗震性能。然而我国规范中,对这种结构的轴压比限值没有给出相应的条文。在工程实践中,设计人员只能套用普通混凝土剪力墙的相关规定,不尽合理。在6片带端柱高性能混凝土剪力墙抗震试验分析的基础上,采用结构三维非线性静力/动力分析程序CANNY,建立了带端柱高性能混凝土剪力墙的力学模型,数值模拟了试件在反复水平加载作用下的受力和变形过程。采用试验研究与数值模拟相结合的方法,研究了带端柱高性能混凝土剪力墙的轴压比限值,为修订规范和工程设计提供参考。High-performance concrete（HPC） shear wall with boundary columns has good seismic behavior.However,the relevant provisions on allowable axial load ratio for this structure are not given in Chinese code.In current engineering practice,the relevant regulations for common concrete shear wall are used by designers although it＇s unreasonable.Based on the seismic experiments of six HPC shear walls with boundary columns,the mechanical model was established and the experimental process was numerically simulated under the repeated horizontal loads by using the 3-Dimensional Non-linear Static/Dynamic Analysis Program CANNY.By combining the experimental research and the numerical simulation,the allowable axial load ratio of HPC shear wall with boundary columns is investigated and discussed,which provides references for amending the code and the engineering design.
