Frattura ed Integrità Strutturale, 2023 There are a few kinds of research about box section Reinforced Concrete (RC) beams under the effect of combined shear and torsional stresses. In the present research, the concept of adding external strengthening, in the transverse direction, is adopted. The paper focuses on using Glass Fiber Reinforced Polymer GFRP ropes as near-surface mount stirrups.

International Journal on Advanced Science, Engineering and Information Technology, 2021 An experimental study has been conducted to explore the response of reinforced self-compacting concrete dapped ends retrofitted with NSM steel bars. Eleven specimens are tested with two shear slenderness ratio values (a/d), namely (1.0 and 1.5). Deficiencies in reinforcement in the nib and hanger zone are considered. The response is studied in terms of

Flexural repair/strengthening of pre-damaged R.C. beams using embedded CFRP rods
Alexandria Engineering Journal, 2015 Many reinforced concrete R.C. elements need either strengthening due to the need of increasing the service loads or repair due to overloading stress or environmental deterioration affecting these elements.

Torsional Strengthening of RC Beams with Near-Surface Mounted Steel Bars
Advances in Materials Science and Engineering, 2020 The strength of reinforced concrete members can be enhanced by using the externally bonded reinforcement (EBR) and near-surface mounted (NSM) methods. However, very few studies have adopted the NSM method for torsional strengthening.
