摘要：玄武岩纤维是一种新型纤维材料，其价格低廉且具较好的延性、耐高温和耐腐蚀特性。对4根玄武岩纤维布加固的无初始损伤混凝土T型截面连续梁进行了抗弯试验，分析了玄武岩纤维布加固混凝土连续梁的破坏模式，并基于纤维布加固混凝土梁的允许拉应变值，对发生延性破坏的玄武岩纤维布加固混凝土连续梁的抗弯承载力进行了计算。 Abstract: As a new fibrous material, the basalt fiber (BFRP) has many advantages in cost, ductility, high thermal resistance and corrosion resistance. Flexural tests were carried out on four nondestructive T-type section continuous beams strengthened with BFRP. The failure modes of continuous beams strengthened with BFRP are analyzed. Based on allowable tensile strain of FRP in flexural strengthening, flexural bearing capacity of strengthened continuous beams under the condition of ductility failure is calculated.
