From the past few decades, there has been a steady growth in the field of construction of building all over the globe. With the technological advances on all fronts the complexity of fires, explosions and the hazards are major challenge thrown up to the planner, engineer and architects. Hence, new techniques and sustainability material have to be adapted for the retrofitting of fire damaged buildings. Notable work has been done with Glass Fibre Reinforced Polymers (GFRP), Carbon Fibre Reinforced Polymers (CFRP) and Basalt Fibre Reinforced Polymer (BFRP) as a fibre reinforced polymers used as a retrofitting material. But less work has been done with geosynthetics material (Gotextiles. Geogrids, Geonets, Geomembranes) . The main purpose of this research study is to evaluate the behaviour of fired RC beam-column joint specimens wrapped with Geogrid and Glass Geocomposite. In the process, 12 beam-column joint specimens were casted out which 9 were fired at a temperature of 600c for 6 hours and 6 specimens were wrapped with the geosynthetics (3wrapped with Geogrid, and 3wrapped with glass fibre) and remaining 3 specimens were tested directly without any wrappings. Studies were performed on the control specimens and the wrapped/ retrofitted specimens for engineering properties. From the result, it has been observed that geogrid wrapped fired specimen and glass geocomposite wrapped fire specimen showed more deflection than control specimen and had higher load carrying capacity than the fired specimen
