Abstract: The ever increasing failure of structures, loss of life and staggering economic losses due to earthquake have raised the concern against earthquake safety to alarming level. Devastating failures in past have witnessed the performance of beam-column junctions governing the global response of structures. Congestion of reinforcement and construction difficulties has escalated the attention required for improved performance of RC beam-column joints. In current study, an attempt has been made to carry out experimental investigations on effect of steel fiber reinforcement near beam column junction on the performance of the joint. The percentage of steel fiber incorporated in the specimen has been fixed at 1.5 % by volume. The effectiveness of measure was experimentally verified. The specimens were tested under horizontal loading and their behavior was discussed with emphasis on strength, stiffness, displacement ductility and failure mechanism. Special attention was also paid to crack width study. It was obtained that specimen with steel fiber had reduced crack width and increased joint efficiency.
