摘　　要：提出了一种用于复杂形式钢筋混凝土框架剪力墙结构空间非线性地震反应分析的方法．整体结构采用空间力学模型．梁柱构件采用可模拟双向弯矩及轴力相互作用的多弹簧杆单元模型．剪力墙采用可考虑中性轴移动的多垂直杆元模型，并将其进行改进，使之能较方便地用于空间分析．对一幢１０层含非平面剪力墙的框架剪力墙结构进行了在强震作用下的非线性分析，结果证明了本文方法和所用单元的实用性．A method is presented for 3 D analysis of nonlinear seismic responses of complex R/C frame wall structures.The multi spring elements that can represent the inelastic characteristics of R/C beams and columns subjected to biaxial bending and axial force interaction is used.The multi vertical line element model that can reflect the movement of the neutral axis of shearwall section is improved and used for simulating the 3 D characteristics of unplane R/C shearwall. The seismic responses of a ten story frame structure with unplane shearwalls are analyzed.The results demonstrate the practical value of the method and the elements.
