Composite GFRP Deck for Bridge Structures

Composite material of glass fiber base is very promising material for future structures. It is possible to create bridge span consists of steel main beams and GFRP deck, according for example ASSET system. The author's research is about parameters of composite material of bridge deck like alternative for concrete one. Identification of kind of glass fiber and type of polymer matrix or type of adhesive with steel or concrete, there are very interesting directions of searching line. The paper will be presented the results of DTA and spectroscopy analysis of GFRP composite, according own paper author's research. It will be described the examples of bridges where GFRP deck have been constructed with main steel beams. The text will give horizon of future author's research of this kind of bridges. Future model stress and fatigue analysis will be showed by main topics. Presented kind of bridges are good alternative for traditional structures by long durability, anticorrosion, light deck with imposing stress parameters. (C) 2012 Published by Elsevier Ltd.
