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 new method for nonlinear seismic response analysis of complex RC frame-shear wall structures is proposed. The overall structure of the spatial mechanics model. Beam-column members adopt a multi-spring-bar element model that can simulate the interaction between two-way bending moment and axial force. The shear wall uses a multi-vertical rod-element model that considers the movement of the neutral axis and improves it so that it can be more conveniently used for spatial analysis. The nonlinear analysis of a 10-story frame-shear wall structure with a non-planar shear wall under strong earthquakes results in the practicality of the proposed method and the elements used.
