［摘要］雙面疊合剪力墻結(jié)構(gòu)是一種新型裝配式結(jié)構(gòu)體系，已在國內(nèi)中低層建筑中推廣應(yīng)用。對于雙面疊合剪力墻結(jié)構(gòu)，其疊合面抗剪性能是保證其整體工作的關(guān)鍵。通過收集自然粗糙面下未植筋新舊混凝土抗剪試驗數(shù)據(jù)，并采用最小二乘法對試驗數(shù)據(jù)進(jìn)行擬合，得到抗剪強度和立方體抗壓強度的關(guān)系。對植筋試件的界面抗剪承載力計算方法進(jìn)行歸納，與雙面疊合試件抗剪試驗結(jié)果進(jìn)行對比，指出雙面疊合剪力墻界面受力情況不同于單面疊合剪力墻，應(yīng)對其受力性能開展進(jìn)一步的研究。

Abstract:The double-superimposed shear wall is a new assembly-type RC structure, which is applied to medium and low-rise buildings in China. The shearing performance of adhesive interface are crucial in developing the monolithic action for doubled\|superimposed shear wall. Through the collection of domestic shear test of the interface of new-to-old concrete without embedded steel bars, the relationship of shear strength and concrete cubic compressive strength was proposed by the least square method. The calculated methods of interface shearing performances for the test specimen with embedded steel bars specified were summarized, and the comparison of test data with calculation result shows that the interface mechanical behavior of double-superimposed shear wall is different from the composite member with single interface, which need further investigation.
Keywords:double-superimposed shear wall; adhesive interface; interface mechanical behavior; bond-slip
