钢纤维轻骨料混凝土无腹筋梁的抗剪性能试验研究

Experimental Study on Shear Behavior of Steel Fiber Light l Aggregate Concrete Beams without Web Reinforcement

通过设置一组配合比下的7个不同参数浇筑钢纤维轻骨料混凝土无腹筋梁做抗剪试验。试验详述了混凝土梁的裂缝开展情况,分析了钢纤维掺量、剪跨比和配筋率对初裂荷载、极限荷载和跨中挠度的影响。

The authors conducted the shear test of steel fiber light aggregate concrete beams without web reinforce- ment by designing a group of mix proportions of seven different parameters. The test details the crack development of the concrete beams. And the steel fiber content, the shear - span ratio and reinforcement ratio influence on the initial cracking load, the ultimate load and the mid -span deflection were analyzed.
