Experimental Investigation of Punching Shear on FRP Strengthened Slab

Abstract

Punching in slabs is generally seen by the application of concentrated loads or to the presence of columns. One of the major phenomenon related to flat slabs is its punching shear capacity at slab column connection. Provided that bending capacity is installed, punching shear failure is due to the development of a truncated cone-shaped surface at the slab-column connection. Frequently, there is the need to strengthen existing flat slabs against punching shear failure. However many research works have been done on punching shear. Moreover, we want to know the behavior of RC flat slab under FRP material against punching shear. The effect of FRP bars against punching shear is checked.The objective of the current study was to explain the feasibility of RC flat slab to examine the application of steel rods, FRP rebar on the improving of punching shear. Extensive applications of the fiber-reinforced polymer (FRP) as new construction materials have been recently accomplished. FRP materials are lightweight, high strength, and no-corrosive materials. By virtue of these advantages, there is a wide range of recent, current, and potential applications of these materials that cover both new and existing structures. Among different types of FRP materials, a fiber-reinforced polymer (FRP) is used extensively in the structural engineering field. This study was carried out to examine the viability of using FRP bars for the punching shear strengthening of the slab.
