【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。更多还原

【Abstract】 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.更多还原
