A novel cost-effective hybrid GFRP/ Concrete deck system consists of the corrugated pultruded GFRP plate with T-upstands for the tension part and concrete with distributing reinforcing bars for the compression part was proposed. Static tests on six full-scale models with different influence factors such as penetrating bars and surface treatment under sagging moments were conducted and observed to evaluate the load-carrying capacity and failure modes of proposed hybrid deck system. Results from experimental work indicate that both surface treatment and penetrating bars improve the connection between GFRP plate and concrete, also promote the ultimate strength and whole rigidity of hybrid deck; moreover the effect of surface treatment is better than that of penetrating bars. The overall investigation showed that the presented hybrid GFRP/concrete concept is a vi-able option for beam-and-slab bridges.
