Abstract


A beam-column joint is very critical element in reinforced concrete (RC) framed structure where the elements intersect in all three orthogonal directions. Joints ensure continuity of a structure and transfer forces that are present at the ends of the members. Beam-column joints in moment resisting frames are crucial zones that control the effective transmission of forces in the structure. In normal design practice for gravity loads, the design check for joints is not usually critical in reinforced concrete (RC) frames and hence not warranted in general. However, failures of RC frames during recent earthquakes have revealed heavy distress in the joints and resulted in the collapse of several structures due to joint shear failure. This paper aims to study the behaviour of beam-column joints in multi-storey RC framed structure with an objective to obtain spatial distribution of joint shear forces which is primarily responsible for failure of RC framed structure subjected to lateral load.  A correlation between joint shear forces and building height has been developed which will help to identify the location of critical joints in a multi-storey RC frames.
