Abstract:The hybrid reinforced method of replacing steel bar with FRP bar (fiber reinforcement polymer bar) in angle region to solve the problem of durability is proposed. Through analyzing the mechanics and service performance of hybrid reinforced concrete beam under the bending moment, the formula of ultimate moment is derived, and the formula is modified by static bending experiment of hybrid reinforcement concrete beams.
Keywords:reinforced concrete beam; fiber reinforcement polymer bar; durability； flexural capacity
