Bursting Stresses in Beam Column Joint Analyzed and Designed as Per Indian Standards

Abstract

There are many cases in which the RC building frames are subjected to failure at the beam column joint (BCJ). This is due to wrong analysis and design of joints. During the analysis of the building frame, we usually assume the BCJ of the frame as fixed joint, but in reality the BCJ are never perfectly fixed one. Due to this, the forces and moments around and the stresses within the BCJ are analysed wrongly than actually induced during the seismic loading. The various countries had updated their codal provisions for the analysis and design of BCJ based on the experiments carried on till now. In this research, it is proposed to study the bursting stresses developed in the BCJ of the proposed building subjected to the seismic loading using the finite element based software (ANSYS). The analysis and design of the building frame and its BCJ's is carried out as per the provisions in draft copy of IS:13920:2014. The BCJ so designed are modelled in finite element based software and subjected to the forces obtained from the performance based analysis of the building to study bursting stresses developed in the BCJ.
