高强钢纤维混凝土弯曲韧性试验研究
Flexural Toughness of Steel Fiber Reinforced High-strength Concrete
【摘要】 通过试验得到了不同基体混凝土强度、钢纤维体积分数和钢纤维类型的高强钢纤维混凝土弯曲荷载-挠度曲线,据此研究分析了基体混凝土强度、钢纤维体积分数和钢纤维类型等对高强钢纤维混凝土弯曲韧性指数和弯曲承载力变化系数的影响规律.该成果可作为纤维混凝土结构技术规程相应设计条款的科研依据.
【Abstract】 The test curves of flexural toughness of steel fiber reinforced highstrength concrete were obtained. The effects of the base concrete strength, steel fiber volume fraction and steel fiber forms on the coefficients of flexural toughness and the variation factors of flexural resistance are analyzed. The test results could be used as a research basis for revising and enlarging the contents of the technical specification for fiber reinforced concrete structures.
