Punching Strengthening of Concrete Slab-column Connections Using Near Surface Mounted (NSM) Carbon Fiber Reinforced Polymer (CFRP) Bars

Ahmed H. Abdel-Kareem · Journal of Engineering Research and Reports · 2020

This paper investigates experimentally the effect of near surface mounted (NSM) carbon fiber reinforcement polymer (CFRP) bars as externally strengthening on the punching shear behavior of interior slab-column connections. Many researchers used NSM as a novel strengthening techni...

Behavior of Concrete Deep Beams Reinforced with Inclined Web Reinforcement around Different Opening Shapes

Ahmed H. Abdel-Kareem & Ibrahim A. El-Azab · Advances in Research · 2019

The objective of this paper is to experimentally and analytically estimate the influence of inclined reinforcement placed above and below web openings having different shapes in reinforced concrete (RC) deep beam. Twenty RC deep beams had the same overall geometric dimensions wer...

Shear Strengthening of R.C Beams with FRP Using (NSM) Technique

Ahmed H. Abdel-Kareem, Ahmed S. Debaiky, Mohamed H. Makhlouf & M. Abdel-Baset · Advances in Research · 2019

This paper presents the experimental results of investigations the shear behavior of strengthened reinforced concrete beams by using glass fiber reinforced polymers (GFRP) rods. The strengthening system used GFRP rods were done by Near Surface Mounted technique (NSM), NSM techniq...

Nonlinear FE Prediction of Shear Strength of RC T-Beams with Flange in Compression Zone

Osman M. O. Ramadan, Ahmed H. Abdel-Kareem, Hala R. Abousafa & Ibrahim A. El-Azab · Journal of Engineering Research and Reports · 2023

This research predicts the shear strength of reinforced concrete T-beams with flanges under compression stresses using nonlinear finite element (FE) analysis. A FE model is developed and verified against specially designed experiments (beams with varying flange width and depth)....
