［摘要］双面叠合剪力墙结构是一种新型装配式结构体系，已在国内中低层建筑中推广应用。对于双面叠合剪力墙结构，其叠合面抗剪性能是保证其整体工作的关键。通过收集自然粗糙面下未植筋新旧混凝土抗剪试验数据，并采用最小二乘法对试验数据进行拟合，得到抗剪强度和立方体抗压强度的关系。对植筋试件的界面抗剪承载力计算方法进行归纳，与双面叠合试件抗剪试验结果进行对比，指出双面叠合剪力墙界面受力情况不同于单面叠合剪力墙，应对其受力性能开展进一步的研究。

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
