Conference Paper
Near Surface Mounted (NSM) fiber reinforced polymer (FRP) technique has become widely used for retrofitting concrete structures. While commonly implemented at the utmost extreme fibers (top or bottom faces), several reasons such as accessibility problems and premature debonding, make the application of NSM FRP technique at the side faces (side-NSM...

Wrapping concrete columns with fiber reinforced polymer (FRP) jackets can result in a significant increase of compressive strength and ductility, and can mitigate deterioration due to aging, chemical attacks, overloading, and seismic activity. Cementitious mortar has recently been used as a binder for FRP reinforcement, leading to a sustainable and...
Conference Paper
In this research, a nonlinear 3D finite element (FE) has been developed to investigate the flexural performance of FRCM strengthened one-way reinforced concrete (RC) slabs.

Fiber reinforced cementitious mortar (FRCM) improves the performance of fiber-reinforce polymer (FRP) by replacing the organic matrix (e.g., epoxy) with inorganic one, resulting in a more sustainable alternative with a much improved fire resistance. While numerous models have been developed for FRP-confined concrete, FRCM-confined concrete have not...
