Paper Details

Beam-Column joints in a reinforced concrete moment resisting frame are crucial zones for transfer of loadseffectively between the connecting elements in the structure. It has been observed that during earthquakes, Corner Jointsare under heavy distress due to shear in the joints which results in the collapse of the structure. The previous studieshave confirmed that corner joints subjected to opening moments are more critically influenced by the detailing ofreinforcement than those subjected to closing moments. In the first part of the study four frames with differentreinforcement detailing arrangement i.e. conventional L-type detailing arrangement (SP1), inverted U-type detailingwith diagonal steel at corner (SP2), inverted L-type detailing with splay steel (SP3) and overlapping U-stirrups typedetailing (SP4) were analyzed using ATENA 2D software. Based on the results from ATENA software in terms ofultimate load, first crack load, crack initiation width and crack width at ultimate load, specimen SP3 was selected forfurther investigations as this specimen performed better structurally. In the second part of study, the effect of differentsizes of chamfer at reentrant corner; the effect of different percentage of tension steel; effect of different percentage ofcompression steel; effect of different spacing of shear reinforcement; effect of different percentage of splay steel; effect ofdifferent grades of concrete; and effect of different percentage of grade of steel were observed on specimen SP3.
