后浇混凝土与砖砌体粘结面抗剪强度的试验研究

Research to shearstrength of bond-interface between concrete and masonry

后浇混凝土与砖砌体粘结面的抗剪强度在砖砌体结构维修、加固改造的设计中是不可缺少的强度指标。根据砖砌体结构房屋材料和混凝土材料使用现状,采用不同强度等级的普通烧结粘土砖和不同强度等级的混凝土,制作了一批双面剪切抗剪试件。通过试验分析,得出了常用的不同强度等级材料在2种材料界面抗剪强度的设计值,为工程应用提供参考。

The shearstrength of bond-interface between concrete and masonry is cratical problem in desigh of strengthing masonry structure. Make tweenfaceshear test member of fired common brick and concrete in different strength class. Achieve shearstrength design value of bond interface between concrete and masonry from test. The shearstrength disign value can be referred to in engineerings.
