Abstract
Strength, ductility of structures differ primarily on appropriate detailing of. beam column joints need a vital role in the structural reliability of the structures given with appropriate stiffness and ultimate strength to maintain the loads transmitted from beam and column. Beam column joints defined as the reinforced concrete buildings, in which portion of columns and beams having their intersections. Although these forces greater than these are affected during earthquakes, joints are relentlessly damaged. As far as earthquake is affected, research on beam-column joint is essential. In HPC, these materials with admixtures are meticulously designated and proportioned to produce very high early, ultimate strengths and durability away from conventional concrete. The admixtures like flyash, silicafume, ground granulated blast furnace slag (GGBFS), which are combined with its strength and durability and boost its marketability as a natural friendly product. The most important purpose of the present study is to investigate the performance of high performance reinforced beam-column joints (replacement of cement with GGBFS). Ground granulated blast furnace GGBFS is employed as a partial replacement of cement with glass fibre and super plasticizer is applied to accomplish required workability. In this study, a evaluation of control specimen and specimen of beam column joint with 7.5% GGBFS and 0.3% glass fibre replacement intended as per IS 456:2000 and IS 13920:2016. Also, to ascertain the performance of beam-column joints subjected to monotonic loading for high performance concrete employing with Ground Granulated Blast Furnace Slag (GGBFS) and glass fibre.

Summary
The importance of concrete structures with high ductility which have revealed again by earthquakes in various parts across the world. Ductility defined as the ability of reinforced concrete sections, elements and structures to enthrall the larger energy emitted during the tremors devoid of losing their strength below greater scale and reversible deformations. Ductility of structures be contingent mostly on appropriate detailing of the reinforcement in beam column joints. GGBFS replacement builds lower heat of hydration, greater stability and improved resistance to sulfate and chloride attack produced with conventional concrete, from a structural view. It lessens the use of cement all over the production of concrete, which fosters to environmental protection. The complement of GGBFS to concrete will alter in a minimal growth in elastic modulus for afforded compressive strength, even if the discrepancies are not huge enough to be importance in design
