摘要:本文建立了一种用于钢筋混凝土剪力墙非线性分析的二维混凝土及钢筋本构模型。该模型对混凝土受压、受拉力学行为分别描述，可以对反复荷载作用下钢筋混凝土剪力墙承载力及变形进行较准确分析。为验证模型适用性，计算单片剪力墙在反复荷载作用下非线性力学行为，结果表明：计算结果反映了剪力墙的滞回特性，初步验证了本文模型的正确性和有效性。
Abstract: In this paper, a 2D constitutive model of concrete and steel for nonlinear analysis of reinforced concrete shear wall is established. The compressive, tensile mechanical behavior of concrete are described respectively. Bearing capacity and deformation of reinforced concrete shear wall under cyclic loading can be analyzed accurately. To verify the applicability of the model, the nonlinear mechanical behavior of the single shear walls under cyclic loading is calculated, the results shows that the model can effectively describe hysteretic characteristics of reinforced concrete shear wall, correctness and effectiveness of this model are verified initially.
