Abstract

The static and fatigue behavior of the foam-filled GFRP bridge deck is presented. The foam-filled GFRP bridge deck consists of a typical modular bridge deck and a soft foam filling the empty space of the modular deck. It is shown that the excessive shear deformation of the modular deck can be greatly mitigated by the foam inside. Consequently the overall load capacity is increased more than 300% with the foam. The elastic stiffness of the foam is the order of a thousand of the homogenized modulus of the GFRP of the deck. As well as the static response the endurance limit of the foam-filled bridge deck is remarkably higher than that of the unfilled bridge deck. The improvement of the structural system will be discussed based on experimental data.
