Abstract |
In the present study, the application of carbon-fiber reinforced polymer (CFRP) to improve the punching shear strength of flat slab has been investigated. The external bonded CFRP was arranged in two orthogonal directions. In one direction FRP rod was mounted in groove and other direction CFRP strip mounded in EBROG technique. The punching shear strength of slab investigated by applies a concentrated load on the centre of slab. The concrete slab specimens were strengthened with 1 or 2 or 3 stacked bars and CFRP strips at each face of loading point in two orthogonal directions and their load–displacement relationships as well as their failure loads were compared with control slab. Experimental results showed that the external bonded CFRP on grooving method enhanced the punching shear load. The results showed the great efficiency of the method so that the punching shear capacity of flat slab with CFRP increased between 28.4 - 58% compare to control slab. |
