Torsional Strengthening of RC Beams with Continuous Spiral Near-Surface Mounted Steel Wire Rope

International Journal of Concrete Structures and Materials, 2020
The strength of reinforced concrete members can be enhanced using externally bonded reinforcement (EBR) and near surface mounted (NSM) methods. However, small number of studies has adopted the NSM method for torsional strengthening. To date, no study has
