摘要
为研究高强钢筋钢纤维混凝土梁在集中荷载作用下的受弯性能,对配置HRB600钢筋的4根钢纤维混凝土梁和4根未掺钢纤维的混凝土梁进行了试验研究。研究结果表明:配置HRB600钢筋的钢纤维混凝土梁的受力性能与普通钢筋混凝土梁相同;掺入钢纤维对承载力有所提高,还可以减小裂缝宽度及挠度。可以按照《混凝土结构设计规范》(GB 50010—2010)中的相关公式计算HRB600钢筋钢纤维混凝土梁的受弯承载力、挠度及裂缝宽度。
To investigate the bending behavior of steel fiber concrete beam with high strength steel bars,the experimental study on four steel fiber reinforced concrete beams and four RC beams with HRB600.The research results show that the mechanical property of steel fiber reinforced concrete beams with HRB600is the same as the common reinforced concrete beams.At the same time,adding to the steel fibers has increased the capacity,and can also reduce the crack width and deflection.The bending capacity,deflection and crack width of steel fiber reinforced concrete beams with HRB600can be calculated according to the relevant formula in Concrete structure design specification.
