摘要
针对震损的混凝土空间框架节点的加固修复方法,本文简要介绍了5个用玄武岩纤维加固的混凝土空间框架节点低周反复试验的情况,对试验现象及实验数据进行了分析,发现加固后的节点极限承载力及延性系数等得到较大的提高,说明该加固方法是合理有效的。
Based on the strengthening and repairing method of the Pre-damaged Beam-Column-Slab Connections,five Beam-Column-Slab Connections are tested under low frequency reversed load.The testing phenomena and test data are analyzed.It is found that after strengthening by BFRP the ultimate strength and tensility of the joints are greatly enhanced.
