摘要: 玄武岩纤维复合材料(BFRP) 是一种新型纤维复合材料,具有价格低、延性好、耐高温和耐腐蚀等优点。为分析玄武岩纤维加固混凝土抗弯构件的受力性能和破坏模式,对4 根玄武岩纤维布加固的混凝土T 形截面连续梁和1 根对比梁进行了抗弯试验。试验表明,玄武岩纤维布加固能显著提高混凝土连续梁的屈服荷载和极限荷载,加固梁表现出较好的延性。

Abstract: Continuous basalt fibre reinforced polymer/plastic(BFRP) is a new fibrous composite. Compared with other fiber reinforced polymer/plastic,BFRP has many advantages in ductility,high thermal resistance,corrosion resistance and cost. Flexural experimental are conducted on four two-span T section continuous beams strengthened with BFRP and one comparative beam. Bearing capacity and failure mode of each beam is studied. The results show that yield load,ultimate load,and ductility of strengthened beams are remarkably increased and improved.

Key words: concrete, continuous beams, flexural experimental
