FRP筋钢纤维高强混凝土梁受弯承载力试验
Experiments on the Flexural Capacity of High-strength Concrete Beams Reinforced with FRP Bars and Steel Fiber
摘要
Abstract
In order to investigate the influence of steel fiber volume fraction and ratio of FRP bars on failure mode and flexural bearing capacity of high-strength concrete beams reinforced with FRP bars and steel fiber, 9 specimens were cast and tested. The results indicate that there are 3 failure modes of high-strength concrete beams reinforced with FRP bars and steel fiber: concrete crush, FRP bars rupture and balance failure, and the failure mode is related to reinforcement ratio of FRP bars and steel fiber volume fraction. The flexural capacity of high-strength concrete beams reinforced with FRP bars and steel fiber is improved by the addition of steel fiber, but the increase of the volume fraction of steel fiber has no significant influence on the flexural capacity of beams. The bearing capacity of high-strength concrete beams reinforced with FRP bars and steel fiber increases with the increase of the ratio of FRP bars.关键词
