Behaviour of Reinforced Cement Concrete Exterior Beam-Column Joints Under Seismic Loading and Techniques of Improving the Joint Ductility

The strength of beam-column junction plays a very important role in the strength of the structure under different loading conditions. Beam column joints can be critical regions in reinforced concrete frames designed for inelastic response to severe seismic attack. Lack of ductility in concrete members raises serious concerns for overall structural safety, especially for reinforced concrete beam-column joints. In the current study, research was performed to improve the seismic strength and performance of reinforced concrete exterior beam-column joints under static and dynamic loads. The exterior beam-column joints are studied with different parameters Maximum principle stress, Minimum principle stress, Displacement, Deformation, Stiffness variation of beam column joint using ANSYS modelling. The objective is to analytically illustrate those to highlight their assets and limitations and to identify future directions in this research area. All these details are presented.
