| 摘 要： | 玄武岩纤维具有优异的耐腐蚀性能，采用玄武岩纤维材料（BFRP）筋代替钢筋是一种解决钢筋锈蚀问题的潜在方法。通过6根试验梁，研究不同剪跨比下BFRP筋混凝土粱的抗剪性能。试验表明，BFRP筋混凝土梁呈脆性破坏，破坏位置集中在分配梁加载点附近；随着剪跨比的减小，斜截面初裂荷载逐渐提高，且逐渐接近于极限荷载；混凝土梁开裂前，挠度增长缓慢，开裂后增长较快，表现为荷载-挠度曲线呈折现变化。

| Abstract: | Basalt fiber has excellent corrosion resistance. It is a potential solution to rebar＇s corrosion by using basalt fiber material tendons （BFRP） instead of bars. Through six test beams, shear properties of BFRP rein- forcement concrete beams were studied with different shear span ratio. The tests showed that BFRP reinforced concrete beams were brittle fail, and failure position focused near the allocation of beam loading point. With the shear span ratio decreases, the first crack load of oblique section gradually increased, and gradually closed to the ultimate load. Deflection grew slowly before the concrete beams cracked and grew rapidly after cracking with discounted changes in the load - deflection curve. |
