Applied MechanicsReinforced Concrete (RC) members in existing RC structures are susceptible to shear-critical due to their under-reinforced design. Thus, implementing a retrofitting technique is essential to eliminate the casualties that could arise from sudden and ...

Journal of Composites for Construction, 2017 Many studies have been carried out on enhancing the positive moment capacity of the midspan areas of RC beams with fiberreinforced polymer (FRP) reinforcement under monotonic increasing loads. The present study focuses on retrofitting of beam support regions under reversed cyclic loading conditions representing seismic conditions.

Flexural retrofit of support regions of reinforced concrete beams with anchored FRP ropes under reversed cyclic loading [PDF]
Proceedings of the Second International Conference on Performance-based and Life-cycle Structural Engineering (PLSE 2015), 2015 Many studies have been conducted for enhancing the positive moment capacity of the mid-span areas of reinforced concrete (RC) beams strengthened with fiber reinforced polymer (FRP) reinforcement under monotonic increasing loads. However under seismic actions, the support regions of beams may also require retrofitting. In such cases, retrofitting should

INNOVATIVE TORSIONAL STRENGTHENING OF RC T-BEAMS USING NSM FRP ROPES
Proceedings of International Structural Engineering and ConstructionThis study addresses the critical need for effective torsional strengthening techniques in reinforced concrete (RC) structures, with a focus on T-beams. Existing methods, particularly those utilizing externally bonded fiber-reinforced polymer (FRP) composites, have been extensively studied for axial, bending, and shear loads, but torsional behavior ...
