【摘要】 为了研究多层单排配筋剪力墙住宅结构,分析单排配筋混凝土剪力墙与双排配筋混凝土剪力墙抗震性能的差异,设计制作了一个1∶4缩尺的4层钢筋混凝土剪力墙结构模型,该模型的一侧墙体配筋为双排钢筋,另一侧墙体配筋为单排钢筋.对其进行了模拟地震振动台试验,研究了其动力特性以及不同烈度地震作用下结构的加速度反应、位移反应和破坏形态.试验表明,单排配筋剪力墙平面内的抗震性能好于双排配筋剪力墙,由于单排配筋翼缘和腹板的共同工作,其平面外性能与双排配筋剪力墙差异不大,单排配筋剪力墙可用于7度和8度区多层剪力墙住宅结构的抗震设计.更多还原

【Abstract】 In order to conduct research on the residential structures of multi-story RC shear wall with single row of steel bars and make comparative study on the seismic performance of RC shear walls with single row of steel bars and that with double rows of steel bars,an experiment has been introduced in the paper,in which an earthquake simulation shaking table test has been applied to a 4-story model of 1/4 scale.In the model,bi-directional steel bars of double rows have been designed to one side while those of single row to another.The model’s dynamic characteristics and responses of acceleration,deformation,and damage features under different level earthquake have been investigated.From the experiment,we have known that the in-plane seismic performance of RC shear wall with single row of steel bars is better than that of double rows,while out-plane performance of them are similar to the collaboration of the flange and the web.Therefore,RC shear walls with single row of steel bars can meet the seismic demands for residential structure with multi-story RC shear walls in areas of seismic intensity 7 or 8 degrees.更多还原
