【摘要】：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。
[Abstract]:In the low intensity, multi-story concrete shear wall structure, whether we can use the reinforcement form with lower requirement than the wall and edge member structure of the current code, is the low intensity area at present. The problems to be solved in the design of multi-story shear wall structure. Through the low cycle repeated loading tests of 7 specimens with low reinforcement shear wall, the failure mode, ductility, bearing capacity, stiffness, energy dissipation capacity, hysteretic performance and so on are suitable for low intensity zone. The performance of low-reinforced shear wall specimens of multi-storey residential structures was evaluated. The variation parameters of the test are section form, longitudinal reinforcement ratio of edge member, stirrups ratio of edge member, reinforcement ratio of horizontal and vertical distribution of wall web plate. Through the comparison and analysis of the test results, the low reinforced shear wall with reasonable design can be used in the low and multi-story shear wall structure in the low intensity region.
