New Reinforcement Detailing for Concrete Jacketing of Nonductile Exterior Beam–Column Joints
Publication: Journal of Performance of Constructed Facilities
Volume 30, Issue 1
Abstract
The observation of failure patterns of different reinforced concrete structures due to earthquakes in several countries has caused critical concern about the performance of beam–column joints. Retrofitting of reinforced concrete (RC) structures can lead to increased stiffness, strength, and failure deformation. This paper introduces a new type of reinforcement detail for the RC jacketing of nonductile exterior beam–column joints. Experimental investigations were carried out on five types of joint specimens keeping a scale ratio of three and were subjected to reverse cyclic loading. The improvement in performance was observed for the retrofitted non ductile exterior beam–column joints using the new RC jacketing than the conventional RC jacketing.
