Study on Application of Steel Fibre Reinforced Self-stressing Concrete in Transforming Old Simply Supported Bridges into Continuous System

Steel Fiber Reinforced Self-stressing Concrete (SFRSSC) is a new type of fiber reinforced composite that contains self-expansive performance and high tensile resistance. It can be used in old bridge reinforcement because when SFRSSC is restrained by steel bars or other terminal conditions, it creates some values of prestressing force to enhance the cracking moments of the continuous beams. The primary objective of this paper is to apply SFRSSC to strengthen old bridges for simply supported beams transformed into a continuous system. First, a computer analysis of the internal force of continuous T-beams with 5 spans is carried out. Second, based on the model experiments of 8 continuous T-beams with 2 spans, the flexural performance of the beams reinforced by SFRSSC layers are investigated. The paper concluded that flexural performance of continuous T-beams strengthened by SFRSSC is greatly improved over that strengthened by conventional concrete.
