ANALYSIS AND EXPERIMENTAL STUDY ON STRENGTH AND BEHAVIOUR OF EXTERIOR BEAM-COLUMN JOINTS WITH DIAGONAL CROSS BRACING BARS AND STEEL FIBRES FOR IMPROVING THE JOINT DUCTILITY

The present work aims to study analytically and experimentally on the seismic performance of exterior beam column joint to improve the joint ductility with non-conventional reinforcement and by using steel fibres. Five joint sub assemblages were tested under reverse cyclic loading applied at the beam end. Beam column joints are critical regions for frames designed for inelastic response to severe seismic attack. The overall structural safety, especially for joints is due to lack of ductility. Different parameter of joint using ANSYS modelling was studied and experimentally verified the results. All these details are presented.
