【摘要】 基于性能的结构抗震设计是指为保证建筑物预期的抗震功能在未来地震中得以实现,而对于具有不用性能目标的建筑结构采取相应的抗震设防标准。框支剪力墙结构由于能形成底部大空间,满足多种需求而在城市建筑中广泛应用。但该结构沿竖向刚度不连续,易在底部形成薄弱层不利于抗震。以某31层框支剪力墙结构为研究对象,采用MIDAS/Gen软件进行数值模拟,从层间位移角、塑性铰分布与结构变形角度采用弹塑性需求谱与改进的能力谱方法对结构进行抗震性能评估。最后,研究了框支层位置与相对刚度对结构抗震性能的影响,从而为此类型结构设计提供参考。更多还原

【Abstract】 The anti-seismic design based on performance is to adopt different Anti-seismic fortification standards for different performance goals of structures. the frame supported shear wall structure are widely used in urban construction because they can form some large spaces to meet multiple needs. In this paper,the author uses MIDAS/GEN to perform numerical simulation analysis of a 31-storey frame supported shear wall structure,and evaluates its seismic performance from the storey drift,the distribution and deformation of plastic hinge by adopting Elastic-plastic demand spectrum and the improved capacity spectrum method. Finally,this paper analyses the influences of structure seismic performance by changing the position of the transfer storey and the Ratio of stiffness between upper and lower storey of transfer storey and provides the references for this kind of structure.更多还原
