Abstract:The concept of the hybrid FRP-concrete design was exploited in a new type of bridge superstructure system. The proposed hybrid bridge superstructure was designed as a simply supported, 10m singlespan, one-lane bridge. The bridge superstructure consists of two bridge decks and each deck is comprised of four Fiber Reinforced Polymer (FRP) box sections combined with a thin layer of concrete in the compression zone. This new design was proposed to reduce the initial costs and increase the stiffness of FRP composite structure. This paper presents the results from the experimental study on a one-third scale model of the hybrid FRP-concrete bridge superstructure. The scale model was subjected to four-points loading to simulate the truck load. The test results indicate that the proposed bridge model meets the stiffness requirement and has an significant reserve strength. ? 2013 Taylor & Francis Group, London, UK.
