玄武岩纤维复合材料抗震加固混凝土结构研究

Study on Seismic Strengthening of RC Structures with Basalt Fiber Composite Materials

很多情况下,由于混凝土结构在地震作用下延性或承载力不足需要对其进行抗震加固。文章以玄武岩纤维(BFRP)为研究对象,分别考察了BFRP原丝加固、BFRP布加固、BFRP筋/布复合加固以及BFRP网格加固这4种加固方法的优缺点及其加固效果,可以为实际工程抗震加固提供一定参考。

It is sometimes necessary to strengthen the existing structures due to their lack of ductility and baring capacity when subject to earthquakes. This paper studies the advantages and disadvantages of 4 different strengthening methods, including BFRP tows strengthening, BFRP sheets strengthening, BFRP bars/ sheets combinational strengthening and BFRP grid strengthening. Their strengthening effects are given and can be used as references for practical engineering.
