摘　　要：联肢剪力墙在地震作用下的非线性分析具有重要的研究意义。本文在改进多垂直杆剪力墙模型基础上,以带刚域的局部纤维模型模拟连梁,两模型结合可很好的模拟联肢剪力墙。在此基础上,推导了所建模型的刚度矩阵并进行计算,与实验结果的对比证明该模型具有较好的计算精度。但连梁模型有待进一步改进,以模拟短梁的剪切影响。It is necessary to analyze the nonlinear response of coupled walls subjected to earthquake.Based on the modified-multi-vertical-line shear wall model,this paper adopted partial fiber model with rigid region to simulate coupling beams.The two models were assembled to simulated coupled walls.Stiffness matrix was deduced.Finally,an example was calculated and compared with test result.However,the coupling beam model should be improved to considering the effect of shear later.
