Strengthening of Rc Slab With Multiple Opening by NSM Technique

Abstract

This paper presents the Near Surface Mounted (NSM) FRP rods are now emerging as a promising technique, in addition to externally bonded FRP laminates, for increasing flexural and shear strength of RC members. Introducing openings in existing reinforced concrete (RC) slabs can severely weaken the slabs due to the cut out of both concrete and reinforcing steel. In this thesis, the use of Glass Fibre Reinforced Polymers (GFRP) strengthening alternatives to restore the flexural capacity of the RC slab after having multiple openings in the slab have been studied.
