Experimental study on rehabilitated rc beamcolumn connections under cyclic loading

Abstract

Post earthquake investigations into damaged structures generally showed that in many cases damages of RC frame structure were localized in beam column connections which might have led to partial or total collapse of the building It was observed that the exterior beam column connections had suffered more in comparison to the interior ones The failure of these connections during past earthquakes opened a new research direction in the field of repair of damaged structures Research in this area
