在低烈度的低、多层混凝土剪力墙结构中,是否可以采用比现行规范规定的墙体和边缘构件构造配筋更低要求的配筋形式,是目前低烈度区低、多层剪力墙结构设计需要解决的问题。通过7个低配筋剪力墙试件的低周反复加载试验,从破坏模式、延性、承载力、刚度、耗能能力、滞回性能等方面对低烈度区采用适合低、多层住宅结构的低配筋剪力墙试件的工作性能进行评价。试验的变化参数为截面形式、边缘构件纵筋配筋率、边缘构件箍筋配箍率、墙体腹板水平及竖向分布钢筋配筋率。通过对试验结果的对比分析,在低烈度区的低、多层剪力墙结构中,能够采用经过合理设计的低配筋剪力墙。
In the low-intensity, low-rise and multi-story concrete shear wall structure, whether the reinforced form with lower requirement of reinforcement than the existing wall and edge components in the existing code can be adopted, Wall structure design needs to be solved. Through the low-cycle repeated loading test of seven low-reinforcement shear wall specimens, the low-lying and multi-story residential structure is adopted in the low intensity region from the aspects of failure mode, ductility, bearing capacity, stiffness, energy dissipation capability and hysteresis performance The performance of the low-reinforcement shear wall specimens was evaluated. The variation parameters of the test are the cross-section form, the longitudinal reinforcement ratio of the edge member, the stirrup ratio of the edge member stirrup, the web wall of the wall and the reinforcement ratio of the vertical distribution. Through the comparative analysis of test results, low and multi-storey shear wall structure in low intensity region can adopt well-designed low-reinforcement shear wall.
