摘要
为研究大震下框架-剪力墙结构三维弹塑性地震反应,采用纤维模型(CANNY99),对九层1:6钢筋混凝土框架-剪力墙结构振动台实验模型进行地震反应分析。在结构主震频率和顶层加速度反应等方面,对数值模拟与实验结果进行对比分析。结果表明:基于纤维模型的三维分析方法能够模拟框架-剪力墙结构的弹塑性地震反应,具有较好的可靠性和稳定性。
Aimed at investigating three-dimensional inelastic earthquake response of frame-wall structures subjected to big earthquake, this paper discribes the adoption of fiber element model to analysis of shaking table tests of a nine story 1 ： 6 scale frame-wall structure model. The paper provides the comparison and analysis of the aspects of natural frequency and top floor acceleration, based on the experimental and analytical results. The results show that three-dimensional analytical method, based on fiber element model allows a better simulation of the inelastic earthquake response of frame-wall structures better and thus exhibits a better reliability and stability.
