摘　　要：为进一步研究钢骨混凝土剪力墙在不同轴压比下的各项抗震性能,明确其受力机能、破坏状 态、耗能机理,为工程设计人员提供合理有效的设计参数,为将来进一步的研究提供基础,本研究以三个 联肢钢骨剪力墙试件的伪静力抗震试验为基础,从强度、变形和能量等三个方面判别和鉴定各试件的抗 震性能。同时利用多种方法计算试件的承载力,计算结果表明,利用现有规范计算钢骨剪力墙抗剪承载 力是精确可靠的。In order to study the seismic performance of steel-encased RC tube under different axial-load ratio, to understand stress mechanism, damage state, energy dissipation mechanism, to build a nonlinear model of steel-encased RC-tube, to provide advisable structural design parameters and to set up foundation for further study, pseudo-static tests of three coupled shear wall elements were conducted. Earthquake-resistance performance of each element is evaluated in three ways: strength, deformation and energy. In addition, shear strength of elements was calculated through many ways. The results show that the shear strength of specimens using existing code is precision and reliable.
