INVESTIGATION OF BEHAVIOUR OF CONCRETE SLAB STRIP RESTARINED BY GFRP WITHOUT INTERNAL REINFORCEMENT

Abstract

Abstract: A arch-shaped concrete slabs strip without internal reinforcement was proposed in this study based on compressive membrane action (CMA). In this novel structure, glass fiber reinforced polymer (GFRP) rods were used as restraint components to develop this membrane action. Therefore, the loading capacity of concrete deck slabs can be enhanced significantly. The behaviour of those concrete strips were studied experimentally. Through the parametric study, it was concluded that the loading mechanism of this slab structure was dependent on internal compressive membrane action and the loading-carrying capacity could be affected significantly by the lateral restraint stiffness. With the application of GFRP material and CMA, the structural durability is improved and the loading-carrying capacity is not affected in this deck structure.

Key words: arch-shaped concrete slabs strip, GFRP bar, compressive membrane action(CMA), experimental test
