摘要
进行了柱加大截面加固框架节点及碳纤维加固框架节点的试验,并对两者在承载力、刚度、延性及耗能能力等方面进行了比较。两种加固方法都改变了节点核芯区脆性破坏的性质,节点核芯区的极限强度、延性、刚度及耗能能力都得以提高。柱加大截面法加固还提高了原节点核芯区的开裂荷载。
Three beam-eolunm joints strengthened by eularging colunm section and four joints strengthened by bonding Carbon Fiber Reinforced Plastic are tested. The strength, stiffness, deflection and energy dissipation of them are analyzed and compared. The results show that the brittleness performances of the strengthened joints are changed, and the ultimate strength, ductility, stiffness and energy dissipation of them are improved. The crack loads of the joints strengthened by enlarging eolunm section are also increased.
