[摘要]在6根钢筋混凝土梁的试验基础上,通过试验梁的开裂荷载、屈服荷载、极限荷载、跨中挠度以及钢筋和玄武岩纤维布的应变等参数,对粘贴玄武岩纤维布加固钢筋混凝土梁的受弯性能、破坏特征进行了分析,提出了相应的设计方法与建议,供工程应用参考。

Abstract:Based on the tests of six RC beams, the flexural behavior and failure type of the test beams strengthened with externally bonded basalt fiber reinforced sheets were researched and analysed through the experimental results of test beams′ cracked load, yielded load, ultimate load, midspan deflection, steel strain and BFRP strain. A calculating method for the ultimate flexural capacity of RC beams strengthened with BFRP is proposed, which can give reference to application.
Keywords:BFRP sheets; RC beams; strengthened; flexural capacity
