| 摘 要： | 为了研究火伤混凝土粘结加固后粘结面的工作性能,对大量遭受高温损伤混凝土与新混凝土的Z形粘结试件进行剪切试验,测得不同温度(20~900℃)、不同冷却方式和不同界面粗糙度情况下粘结面的剪切滑移曲线,拟合出相应的计算公式,并概括粘结面剪切滑移曲线的变形特点。

| Abstract: | In order to study the bonding performance of adhesive reinforcement of fire-injured concrete, a large numbers of shear experiments on Z-shape bonding specimens based on injured concrete subjected to elevated temperature were done. Shear slipping curves were measured under several circumstances such as different temperature, different cooling ways and different interfacial roughness. At same time, the corresponding calculation formulas are deduced and the feature of shear slipping curve is also generalized. The study will provide reference for numerical simulating calculation of bonding reinforcement. |
