简介
Available flexural strength formulas mainly focus on rectangular concrete beams exclusively prestressed with fiber-reinforced polymer (FRP) tendons. Moreover, an iterative procedure is required when FRP rupture governs the design. This paper presents a simplified and yet rational analytical approach for flexural capacity of prestressed concrete T-beams with bonded FRP tendons and non-prestressed steel bars. First, a sectional analysis assuming balanced failure is conducted to distinguish tension and compression failure. In conjunction with a statistical analysis of an experimental database of 87 beams, a new transition region between tension- and compression-controlled sections is proposed in terms of ratio of provided-to-balanced reinforcement () instead of the traditional net tensile strain limits in current American design guidelines. Then, a numerical sectional analysis of tension-controlled …
