［摘要］介紹了4個剪跨比為2.25的預(yù)制鋼筋混凝土剪力墻試件的擬靜力試驗(yàn)，試件的豎向鋼筋采用留洞漿錨、間接搭接的方式連接。試驗(yàn)結(jié)果表明：間接搭接能傳遞鋼筋應(yīng)力；預(yù)制墻試件的鋼筋受拉屈服、混凝土受壓破壞，但其破壞形態(tài)與現(xiàn)澆墻試件有區(qū)別；試件的水平力-位移滯回曲線飽滿，極限位移角為1/42～1/36；可采用規(guī)范公式計(jì)算預(yù)制墻的受壓承載力；豎向現(xiàn)澆帶能將預(yù)制墻連接成為整體，預(yù)制墻側(cè)面采用粗糙面的連接性能優(yōu)于鍵槽的連接性能。

Abstract:Quasi-static tests of 4 pre-cast reinforced concrete shear wall specimens with shear span ratio of 2.25 were introduced. The vertical reinforcements of the specimens were grouted in holes and spliced indirectly. The test results indicate that the indirect spliced vertical reinforcements can transfer stresses. For the pre-cast wall specimen, the vertical reinforcements yield in tension and the concrete fail in compression. The failure mode of the pre-cast wall specimen is different from that of the cast-in-site wall specimen. The lateral load-displacement hysteretic loops of the pre-cast wall specimens are plump, the ultimate drift ratio is 1/42～1/36. The current code formulas are suitable for calculating the compressive strength of the pre-cast shear walls. The cast-in-site stripe can connect the pre-cast walls to be an unit, the integrity behavior of the rough interface of the side face of pre-cast wall is better than that of the shear keys.

Keywords:pre-cast shear wall; grouted in hole; indirect splicing; seismic behavior; quasi-static test
