Enhancing The Performance of Beam-Column Joint Using Artificial Fibers

Abstract

In recent seismic events, numerous moment-resisting reinforced concrete frame buildings have experienced collapse due to shear failure at beam-column connections. Evidence from these earthquakes indicates that compromised beam-column joints significantly undermine the overall structural integrity of the buildings. The overall ductility of structures is also reduced considerably by brittle joint shear failure; As a result, dangerous failure mechanisms emerge. A variety of techniques have been developed to strengthen beam-column joints. Steel and concrete jacketing are examples of these techniques. A novel technique for enhancing structural components has been recognized for over a decade, utilizing fiber-reinforced polymer (FRP) as externally bonded reinforcement in critical areas of reinforced concrete (RC) elements. This paper investigates the impact of glass fiber-reinforced polymer wrapping on corner beam-column joint frames subjected to ultimate loads. The specimens prepared for this study will measure 700 mm x 700 mm, with a cross-sectional dimension of 200 mm x 100 mm. Twelve concrete specimens will be integrated with glass fiber-reinforced polymer to ensure adequate reinforcement.
