Abstract

In any structure, beam column joints are the most critical element, when it is subjected to earthquake loading, but in most of the construction works beam column joints are not designed. Therefore, in earthquake prone area the failure of structure occurred due to beam column joint effect. Hence, it is very essential to design any structure by considering the effect of beam column joint. The aim of this work is to improve the strength of beam column joint and its ductile behavior. In this research work, seismic behavior of various types of joints like exterior, interior and corner were studied by using finite element software ANSYS. Numerical analysis is carried out using ANSYS software. Beam column joints are designed as per IS 13920- 2016. The most important factors affecting the shear capacity of exterior RC beam-column joints are concrete compressive strength, the joint aspect ratio of the joints and number of lateral ties inside the joint. Behaviour of beam column joint with beam weak in flexure and observed stresses in joints also studied. It is observed that exterior joints are more affected as compared to other type of joint by considering the effect of stress.
