【摘要】 对 1 5根钢筋混凝土适筋梁粘贴碳纤维片材加固后的抗弯性能进行了试验研究 ,在试验的基础上对加固后试件胶层 -混凝土界面粘结失效导致的破坏形式进行了分析 ,提出应当对加固材料的极限应变进行限制 ,在加固中宜采用中等强度的粘贴材料更多还原

【Abstract】 Externally bonding carbon fiber reinforced polymer(CFRP)laminates is a new procedure of structural retrofitting.Based on the experiment of 15 RC beams strengthened with CFRP laminates,the forms of epoxy concrete interface bond abating are analyzed.It is suggested that the ultimate strain should be limited and material with lower strength is a better choice.更多还原
