【摘要】：在低烈度的低、多層混凝土剪力墻結(jié)構(gòu)中,是否可以采用比現(xiàn)行規(guī)范規(guī)定的墻體和邊緣構(gòu)件構(gòu)造配筋更低要求的配筋形式,是目前低烈度區(qū)低、多層剪力墻結(jié)構(gòu)設(shè)計(jì)需要解決的問題。通過7個(gè)低配筋剪力墻試件的低周反復(fù)加載試驗(yàn),從破壞模式、延性、承載力、剛度、耗能能力、滯回性能等方面對低烈度區(qū)采用適合低、多層住宅結(jié)構(gòu)的低配筋剪力墻試件的工作性能進(jìn)行評價(jià)。試驗(yàn)的變化參數(shù)為截面形式、邊緣構(gòu)件縱筋配筋率、邊緣構(gòu)件箍筋配箍率、墻體腹板水平及豎向分布鋼筋配筋率。通過對試驗(yàn)結(jié)果的對比分析,在低烈度區(qū)的低、多層剪力墻結(jié)構(gòu)中,能夠采用經(jīng)過合理設(shè)計(jì)的低配筋剪力墻。
[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.
