Filament-wound glass fiber reinforced polymer bridge deck modules
This paper describes a new innovative glass fibr reinforced polymer (GFRP) bridge deck design patented in Canada. The proposed series of GFRP decks were designed and manufactured based on the filament winding technique, which uses fiber rovings. This paper presents the experimental investigation and analytical model used to study the performance of the patented deck. Conclusions from the testing program are summarized below. The GFRP deck is capable to support an HS30 AASHTO design truck load. Modification of the manufacturing process in the second generation eliminated: 1. Premature failure due to buckling and delamination of the outer plates and 2. slippage of the filler bars in the section. Axial strains along the plate span were symmetric and well distributed. Axial strains across the plate width were uniform, indicating that all tubes were resisting load equally. Maximum compressive and tensile strains were reduced and easily met the requirements for prevention of creep rupture. Using Classical Laminate Theory, the analytical model is capable of prediction of the load-deflection behavior of the decks up to service load level.
