摘要
由于直交梁的存在,混凝土空间框架节点核心区无法象平面框架一样直接加固。针对这一工程难题,采用两种碳纤维布加固核心区外侧梁、柱端的方法,进行了五个足尺混凝土框架节点的低周反复加载试验,以检验加固后节点核心区抗剪性能的改善效果,并针对不同加固方法,对碳纤维布的增强机理进行了分析研究。
Cores of RC beam-column joints in two-way frames can＇t be directly upgraded as that in one-way frames because of the existence of two-way beams. In this paper, five full-scale beam-column joints are tested under quasi-static cycle load, to evaluate the shear performance improvement of beam-column joints upgraded by two different CFRP sheets strengthening methods that are around core, and the strengthening mechanism is also presented for different methods.
