摘　　要：将钢筋混凝土框架－剪力用结构离散为能摸拟梁、柱、墙抗震性能的单元，采用杆系－层间模型进行结构的非线性抗震分析。本文的空间力学模型可考虑局部楼板变形对结构地震反应的影响，并可沿任意角度输入相互垂直的两个地震动水平分量，适用于框架－剪力墙复杂结构的非线性抗震分析。ln this paper reinforced-concrete frame-wall structures are divided into elements that can simulate the aseismic characteristics of beam, column and wall. A space combined member-story model is used for analysing the nonlinear seismic responses of buildings. The model, in which the effects of deformation of local floor and the propagational direction of two-dimension earthquake excitation is considered, is adapted to the aseismic analysis of complex frame-wall structures.
