混杂配筋(钢和FRP筋)梁正截面受弯设计方法研究

DESIGN METHOD FOR NORMAL SECTION OF HYBRID REINFORCED (STEEL AND FRP BARS) BEAMS UNDER BENDING

  • 摘要: 钢和纤维复合筋混杂增强混凝土(hybrid reinforced concrete,Hybrid-RC)梁具有较好的承载力、耐久性和延性。然而,基于文献调研发现,现有设计方法对Hybrid-RC梁正截面受弯的破坏形态还未能做出准确的预测。因此,该文修正了现有的设计方法,并通过数据库对比,验证了其有效性。在此基础上,对Hybrid-RC梁提出了一种新的设计思路,以减少使用成本,并得到更高的使用荷载。

     

    Abstract: The hybrid reinforced concrete (Hybrid-RC) beam consisting steel bars and fiber-reinforced polymer bars can provide better bearing capacity, durability and ductility. However, literature review showed that the design methods for the normal section of Hybrid-RC beams under bending failed to predict the failure mode of these structures accurately. Therefore, it revises the existing design method, and verifies its effectiveness through database comparison. On this basis, a new design idea of Hybrid-RC beam is proposed to reduce the service cost and achieve higher service load.
