Static and fatigue testing of hybrid fiber-reinforced polymer-concrete bridge superstructure
This paper presents the experimental results from static and fatigue testing on a scale model of a hybrid fiber-reiforced polymer (FRP)-concrete bridge superstructure. The hybrid superstructure was designed as a simply-supported single span bridge with a span of 18.3 m. Three trapezoidal glass fiber-reinforced polymer (GFRP) box sections are bonded togther to make up a one-lane superstructure, and a layer of concrete is placed in the compression side of those sections. This new design was proposed in order to reduce the initial costs and to increae the stiffness of GFRP composite structures. Static test results showed that the bridge model meets the stiffness requirement and has significant reserve strength. The bridge model was also subjected to two million load cycles to investigate its fatigue characteristics. The fatigue testing revealed that the structural system exhibits insignificant stiffness degradation.
