Behaviors of Void Slab with GFRP Reinforcement

Article Preview

Abstract:

Use of hollow material in slab can reduce self-weight and deflection than solid slab with GFRP reinforcement. In this study, bending tests were carried out to evaluate the bending performance of void slabs with GFRP reinforcements. Test results showed that bearing capacity at the compression zone seriously affected the ultimate bending strength of void flexural members. For a design of the void flexural members with GFRP bars, it needs to use the higher concrete strength and to arrange the void foams considering of the crushing failure and distribution of strains and stresses.
