Description
Summary:Fibre reinforced polymer (FRP) composites have become an integral part of the construction industry because of their versatility, high strength-to-weight ratio, enhanced durability, resistance to fatigue and corrosion, accelerated construction and lower maintenance and life-cycle costs. However, all-composite structural bridge systems have specific shortcomings such as high initial costs, low stiffness and existence of brittle failure modes. To make the best use of materials and overcoming the above shortcomings, combinations of FRP and conventional materials have recently been investigated. The innovative hybrid idea of a "FRP composite-concrete" structural system for bridges has been proposed. The objective of the paper is the description of the bridge itself and the presentation of research results on its development. The finite element model (FEM) analysis, vacuum assisted resin transfer moulding (VARTM) manufacturing technique used for FRP girder production, some research results on the bridge system and demonstrative bridge construction are briefly presented.
