| 摘 要： | 在框架-剪力墙结构内力变形分析方法的基础上,推导了壁式框架-剪力墙结构的刚度特征值计算公式,理论分析了剪力墙结构变形特征随壁式框架比例和房屋高度的变化规律,并采用弹性反应谱法进行了计算验证。采用静力弹塑性分析法,以层位移和层间位移角分布,以及结构塑性铰发展过程为指标,研究了壁式框架比例和房屋高度对结构抗震性能的影响。研究结果表明,壁式框架对剪力墙结构体系抗震性能带来不利影响,应根据其底部承担的倾覆力矩比例分别执行局部构件加强、控制结构高度等的设计规定。

STUDY OF UNIDIRECTIONAL WALL FRAMES' INFLUENCE ON THE SEISMIC PERFORMANCE OF SHEAR WALL STRUCTURE |

| Abstract: | Based on the internal force and deformation analysis method of frame-shear wall structure,the equation of stiffness characteristic coefficient of wall frame-shear wall structure was derived to analyze the deformation characteristics of structures with different wall frames ratio and height of house.The results of theoretical analysis was verified by elastic response spectrum calculation.Through static elasto-plastic analysis,the seismic performance of structures were evaluated by interlayer displacement angle and plastic hinge development process.The research results show that the wall frames bring adverse effects on the structural seismic performance,so the different design regulations such as strengthening of member and control of structure height should be implemented according to the overturning moment proportion of wall frames. |
