Static test of the full-scale hybrid „FRP composite – concrete” bridge girder The new hybrid bridge girder has been presented, in which FRPcomposite and concrete are composed together in order to optimize the efficient utilization of the advantages of both structural materials. Hybrid girders characterize high strength, stiffness and durability aswell as good dynamic behavior and safe, pseudo-plastic failuremode. Themain testing goal of the full-scale hybrid bridge girder has been the evaluation of its static behavior under the 4-point bending and the assessment of ultimate carrying capacity and failure modes. The test results revealed the high load bearing capacity and stiffness of the girder and allowed to assess the local failures in the composite body. They confirmed also required load bearing capacity design and adequate safety margin (regarding to girder’s utilization in prototype road bridge construction).

Keywords: hybrid structure, FRP composite, lightweight concrete, load bearing capacity, static test, road bridge.
