Abstract

This study presents a numerical investigation on structural performance of reinforced concrete (RC) beam-column joints (BCJ) with beam weak in shear subjected to cyclic loading. Retrofitting techniques are explored, utilizing Glass Fiber Reinforced Polymer (GFRP) for shear strengthening, in accordance with ductile detailing standards outlined in IS 13920:2016. The column and beam elements are designed following the guidelines of IS 456:2000. Various specimen scales, including full-scale, 2/3-scale, and 1/3-scale specimens, are employed for comprehensive analysis. Two main scenarios are considered: firstly, employing 100% shear reinforcement in the beam; and secondly, a mixed approach with 70% shear reinforcement in the beam and 50% shear reinforcement in the column. The study aims to assess the effectiveness of GFRP retrofitting in enhancing the shear capacity of beams while evaluating the influence of different reinforcement configurations on the overall structural performance of RC beam-column joints subjected to cyclic loading. Research on joint behavior in BCJs has dived into the significant dynamics of BCJs, enhancing our grasp of their failure mechanisms and performance across various load conditions. Moreover, investigations into shear strength have contributed to refining design principles and retrofitting methods aimed at improving the resilience and ductility of BCJs. It is concluded that the GFRP wrapping has enhanced the shear strength of beam as well as joint.
