【摘要】 为研究冻融循环对CFRP与烧结粘土砖界面的影响,通过一种简单易行的单面剪切试验方法测定了冻融作用下粘贴了碳纤维布的粘土砖试件的应变值,得到荷载-滑移曲线,分析了冻融循环作用下CFRP与烧结粘土砖粘结性能的变化规律,建立了冻融循环作用下CFRP-粘土砖界面荷载滑移退化模型。通过对比分析,模型预测值与试验值吻合较好。更多还原

【Abstract】 In order to investigate the effects of freeze-thaw cycle on the interface of clay brick masonry strengthened by CFRP. The strain values and the load-slip curve of CFRP and clay brick interface were obtained through single shear test. The change law of bonding performance between CFRP and clay brick under freeze-thaw cycles was analyzed, and a degradation model of interfacial load-slip relationship between CFRP and clay brick was established. Through comparative analysis, the predicted values of the model are in good agreement with the experimental values.更多还原
