摘　　要：基于纤维模型概念,提出了一种便于钢筋混凝土高层框架-剪力墙结构空间非线性分析的带边柱剪力墙单元模型。将墙体和边柱视作一个整体单元,导出了相应刚度矩阵。用细分的纤维元模拟混凝土和钢筋的线性和非线性特性,墙元用平面纤维元模拟,柱元用空间纤维元模拟,在考虑墙、柱构件各自受力特点的同时,保证了模型的整体协调性。编制了可应用于钢筋混凝土高层框架-剪力墙结构空间分析的计算机程序。两个算例证明了该文模型的正确性和有效性。A three dimensional （3D） model is put forward in the nonlinear analysis of reinforced concrete shear walls on the basis of a fiber model. The model can be applied to the spatial nonlinear analysis of frame-shear wall structures in high-rise buildings. The wall and the side columns are undivided, and its stiffness matrix is established. The linear and nonlinear characteristics of the concrete and the steel bar are simulated by the fiber elements, the wall is simulated by plane fiber elements and the side coltunn is simulated by spatial fiber elements. The coordination of the whole model is guaranteed while considering the characteristics of the wall and the side columns, which are subject to stress. A computer program for 3D analysis of reinforced concrete frame-shear wall structure in high-rise buildings has been designed. The two examples can prove that the model is both correct and effective.
