型钢混凝土剪力墙轴压比计算及其限值研究

型钢混凝土剪力墙构件具有良好的抗震性能，已在高层和超高层建筑中得以广泛应用。然而我国规范中，对这种结构的轴压比计算方法及限值问题没有给出针对性的条文，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，限制了这种新型结构的推广。本文通过ANSYS程序分析了若干在轴向压力作用下的型钢混凝土剪力墙构件，得到了墙底截面处型钢与混凝土的应力分布情况，从而推导出型钢混凝土剪力墙构件的轴压比计算公式；另外，通过构件低周反复加载试验与计算机数值仿真技术相结合的方法，分析了型钢混凝土剪力墙构件的轴压比限值问题，并提出了设计建议。

Study on axial compression ratio calculation and limit value for steel reinforced concrete walls

Steel reinforced concrete walls have been applied to some high-rise and super high-rise buildings because of its excellent seismic property. Unfortunately, there is no related code involving axial compression ratio calculation and limit value for SRC walls. This restricts the application of this structure significantly. In this article, the stress of structural steel and concrete at the bottom of SRC walls were analyzed with the program ANSYS, then on this basis, the formula for calculating the axial compression ratio was deduced. In addition, on the basis of experiment of SRC walls, with the help of program CANNY, the limit value of axial compression ratio of SRC wall was analyzed and proposed for seismic design.
