A Review on NSM-CFRP technique using in Shear Strengthening of RC Deep Beams


Near-Surface Mounted (NSM) using Fiber-Reinforced Polymer (FRP) bars has been become an effective technique to improve flexural and shear behavior of existing and or new Reinforced Concrete (RC) elements. This is an innovative and emerging technique and much attention has been given by researchers. Thus, this paper attempts to review past and present studies related to the shear strengthening of RC deep beams using NSM-CFRP bar. The past and present research results were obtained through four major databases namely: ASCE, EBSCO, SCOPUS and Science Direct. The careful concern has been taken to review the literature focusing on NSM-CFRP in shear strengthening. The total final set of 56 articles categorized into three main classes. Class 1 comprises on the review studies on the usage of NSM for shear strengthening. Class 2 includes articles related to the structural behavior of RC members’ strength in shear. Class 3 includes articles related to theoretical aspects of the NSM-FRP on shear strength for developing a new approach to calculate shear influences provided by NSM-FRP. In conclusion, this study identifies three basic characteristics of this field: (1) the motivation of using NSM-FRP bars in shear and its applications, (2) open challenges and hindering utilization and (3) the recommendations to improve the acceptance and use of NSM-FRP bars.
