摘要

摘要: 对构件在受剪状态下两种不同的玄武岩纤维增强复合材料(BFRP)箍筋抗拉试验方法进行描述,模拟BFRP箍筋在构件中的受力状态,一种为L型BFRP箍筋抗拉试验方案;另一种为U型BFRP箍筋抗拉试件。通过试验对比了两种构件在抗剪下箍筋的抗拉力学性能,分析两种箍筋试验方案的性能差异,提出C30混凝土构件受剪条件下的BFRP筋抗拉强度建议公式。

Abstract: Two different BFRP stirrups tensile test methods were described when the members were in the shear state,which could imitate the real stress of such stirrups.One was for L-type BFRP stirrup test,the other was for U-shaped BFRP stirrup tensile test.It was compared the tensile mechanical properties of the stirrups in two components under shear state,and was also analyzed the difference of the two methods.Furthermore,a recommended formula of basalt fiber reinforcement plastics tensile strength when C30 concrete structures under shear conditions was proposed.
