摘要
为深入研究采用套筒浆锚连接的装配式钢筋混凝土剪力墙基础隔震结构的受力性能,设计了3个1/4缩尺三层现浇混凝土剪力墙结构、套筒浆锚连接装配式混凝土剪力墙结构与套筒浆锚连接装配式混凝土剪力墙隔震结构试件。通过低周反复水平荷载试验探究了3个试件不同的裂缝开展规律、塑性发展次序、破坏形态、滞回曲线、耗能能力以及隔震支座变形特性等受力性能。试验结果表明:套筒浆锚连接装配式混凝土剪力墙基础隔震结构可以有效地避免上部装配式混凝土剪力墙结构在接缝处出现剪切滑移破坏,并具有优越的耗能能力。
For an in-depth research on the mechanical performance of the precast reinforced concrete shear wall base isolation structure via grout sleeve splicing,three 1/4 scaled-down three-storey structural models were designed respectively,including a integrated cast-in-situ shear wall structure,a precast concrete shear wall structure with grouted sleeve connections,and a based-isolated precast concrete shear wall structure with grouted sleeve connections.By conducting low-cycle repeated horizontal load tests,the crack development law,the plastic development sequence,the failure pattern,hysteresis curve,energy dissipation,deformation of the isolation bearing and other mechanical performance parameters of the three scaled-down samples were studied.The experimental results show that the precast concrete shear wall base isolation structure via grout sleeve splicing can effectively avoid the shear slip failure of the upper precast concrete shear wall structure at the joints and has the superior energy consumption capacity.
