Rational Approach for Evaluating Fire Resistance of Prestressed Concrete Beams Strengthened with Fiber-Reinforced Polymers
Published on 2025-10-16 by Venkatesh Kodur, Tejeswar Rayala, Hee Sun Kim @MDPI
Abstract: A rational approach is proposed for evaluating the fire resistance of fiber-reinforced polymers (FRP)-strengthened prestressed concrete (PC) beams. This approach expands on conventional fire design principles for PC beams, while incorporating the effects of FRP reinforcement and fire insulation into strength calculations under fire exposure. Simplified equations are utilized to evaluate the cross-sectional temperature distribution in fire-exposed FRP-strengthened PC beams, considering both insul[...]
Our summary: A rational approach evaluates the fire resistance of FRP-strengthened prestressed concrete beams. Simplified equations assess temperature distribution and strength reductions due to fire exposure. Results indicate that fire insulation significantly enhances load-bearing capacity compared to uninsulated scenarios.
