A State-of-the-Art of Flat-Slab Connections Reinforced with GFRP Bars under Gravity and Lateral Loading

Abstract: Flat plates are widely used in reinforced concrete (RC) structures due to their functional and economic advantages. Their design is usually governed by the punching shear stress surrounding the slab-column connections. In seismic zones, slab-column connections must possess adequate strength and ductility to undergo inelastic deformations without fail during and after the earthquake occurrence. Nowadays, fiber-reinforced polymer (FRP) reinforcing bars have gained wide acceptance in the construction industry to use effectively as an alternative to steel bars, particularly when steel corrosion is a major concern. Concerns are questioning the applicability of using the FRP as longitudinal and transverse reinforcements in the slab-column connections under lateral loads. Due to the growing use of GFRP bars in flat slab parking structures and such field applications, there is a need for a deeper knowledge of the behavior of these elements as part of the whole system of the building. This paper presents a critical review of the state of the art of experimental and analytical research concerning the punching shear response of RC flat slab reinforced with GFRP bars subjected to gravity load and lateral loads. Besides, the newly developed techniques and innovations for enhancing the punching shear behavior of flat slabs totally reinforced with FRP are highlighted.
