［摘要］為深入研究采用套筒漿錨連接的裝配式鋼筋混凝土剪力墻基礎(chǔ)隔震結(jié)構(gòu)的受力性能，設(shè)計了3個1/4縮尺三層現(xiàn)澆混凝土剪力墻結(jié)構(gòu)、套筒漿錨連接裝配式混凝土剪力墻結(jié)構(gòu)與套筒漿錨連接裝配式混凝土剪力墻隔震結(jié)構(gòu)試件。通過低周反復(fù)水平荷載試驗(yàn)探究了3個試件不同的裂縫開展規(guī)律、塑性發(fā)展次序、破壞形態(tài)、滯回曲線、耗能能力以及隔震支座變形特性等受力性能。試驗(yàn)結(jié)果表明：套筒漿錨連接裝配式混凝土剪力墻基礎(chǔ)隔震結(jié)構(gòu)可以有效地避免上部裝配式混凝土剪力墻結(jié)構(gòu)在接縫處出現(xiàn)剪切滑移破壞，并具有優(yōu)越的耗能能力。

Abstract: 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.
