摘要:
对18组钢-聚丙烯混杂纤维高性能混凝土深梁试件和2组高性能混凝土深梁对比试件进行受剪试验,分析混杂纤维高性能混凝土深梁受剪破坏过程及破坏形态,探讨混杂纤维对高性能混凝土深梁剪切初裂强度及抗剪极限强度的影响.结果表明:掺入适量的钢-聚丙烯混杂纤维,可使深梁水平及竖向分布钢筋应变明显减小,剪切延性得到提高.掺入混杂纤维后,无腹筋深梁剪切初裂强度平均提高20.3%,抗剪极限强度平均提高17.2%;有腹筋深梁剪切初裂强度平均提高70.1%,抗剪极限强度平均提高33.9%.
Abstract:
Shear behavior was studied on 18 different groups of deep beams with steel fiber and polypropylene fiber and 2 groups contrastive HPC deep beams based on experiment. The process and the mode of shear failure of hybrid fiber reinforced high performance concrete deep beams were analyzed. The effects of hybrid fiber on the diagonal cracking strength and the shear strength of HPC deep beams were explored. The results show that hybrid fiber can be used to reduce the strain of web horizontal reinforcement and web vertical reinforcement and increase shear ductility of deep beams. The average diagonal cracking strength is increased by 20.3% and the average shear strength is increased by 17.2 % when HPC deep beams without web reinforcement are mixed into hybrid fiber. The average diagonal cracking strength is increased by 70.1% and the average shear strength is increased by 33.9 % after hybrid fiber added into HPC deep beams with web reinforcement.
