摘　　要：带边框低矮抗震墙在建筑结构设计中应用广泛,其受力性能复杂,在地震作用下一般发生剪切破坏。以试验研究及有限元分析结果为基础,分析了带边框低矮抗震墙的承载机理。利用等效斜压杆的方法,给出了无洞及开洞带周边框架RC低矮抗震墙的受剪承载力和不同受力阶段刚度的计算公式,并与试验结果进行了比较。研究结果可供设计计算时参考。RC framed squat wall is widely used in RC frame-wall structures and its shear strength and stiffness are difficuh to be analyzed for its complicated resistant mechanism. The lateral resisting mechanism of RC framed squat wall is established based on test results and finite element analysis. A practical method and formulas for evaluating the shear capacity and the stiffness of the RC framed squat wall are proposed. The comparison result of the calculation and the tests indicates that the proposed method can be reference for engineering practice.
