Abstract

A new type of GFRP bridge decks is proposed. The space of each module was filled with a polyurethane foam of which elastic modulus is about 10MPa. Although the modulus of the foam was only a thousand of the apparent modulus of the GFRP laminate for the deck, the structural behaviours in the transverse direction such as the nominal strength, stiffness, etc. were greatly improved compared to those of the reference decks of which space was left empty. Because of the low weight of the foam, the bridge deck was still light enough. Webs of this type of deck did not significantly contribute to the strength development. The strength of the deck in the longitudinal direction was increased about 20%, too.
