Shear Strengthening of Concrete Members Using NSM Method

This article describes the shear strengthening of reinforced concrete structures with one of the latest and most promising method: NSM - Near surface mounted reinforcement. Research in this area started only a few years ago with a combination of epoxy and FRP (fiber reinforced polymer) materials suitable for strengthening concrete elements. In this paper main components of NSM strengthening systém are described, design approaches and also numerical models of strengthened concrete beams are also mentioned.
