Lightweight Self-consolidating Concrete Bridge-Deck Slabs Reinforced with GFRP Bars Under Concentrated Loads
Advances in new mix designs in lightweight self-consolidating concrete (LWSCC) have led to the construction of new concrete structures with much lower weight and higher strength. The combination of LWSCC and GFRP bars can lead to have smaller cross-sections in bridges and less structural weight. This study aims to evaluate the efficiency of this type of concrete in the construction of GFRP-reinforced bridge deck slabs. For reaching this goal, this experimental project includes testing of full-scale edge-restrained concrete deck slabs, simulating a slab-on-girder bridge deck commonly used in North America and were designed according to Canadian standard CSA S6-19. The bridge-deck slabs have 3,000 mm in length, 2,500 mm wide, and a thickness of 200 mm. The slabs were tested up to failure over a center-to-center span of 2,000 mm under a single concentrated load acting on the center of each slab over a contact area of 600 × 250 mm to simulate the footprint of a sustained truck wheel load (87.5-kN CL-625 truck) as specified in Canadian standards. The failure mode of all deck slabs was punching shear. Recorded ultimate load capacities for all specimens exceeded the design factored load which can validate the use of GFRP-reinforced LWSCC in the construction of bridges.
