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,并对二者在承载力、刚度、延性及耗能能力等方面进行了比较与分析,结果表明,柱加大截面加固试件刚度及耗能能力提高比碳纤维加固试件提高大,碳纤维加固试件的延性有稳定提高,柱加大截面加固试件延性变化情况不稳定,与核心区是否配箍密切相关。
The test of RC frame joints strengthened by enlarging column section or by bonding carbon fiber reinforced plastics are conducted in this paper. The strength, stiffness, ductility, energy dissipation between two kinds of samples are compared and analysed. The former got a better increase than the latter in stiffness and energy dissipation, but the latter obtained stable ductility rise. The former ductility was influenced by the stirrup in the core, and varied unstably.
