Beam-Column Joint plays an imperative part in the seismic enactment of Reinforced concrete moment resisting frame. The response of the structure under the earthquake loads mainly depends on the behavior and performance of the Beam-Column Joint (BCJ). An experimental investigation on exterior reinforced beam-column joints done using steel fibre reinforced self-compacting concrete subjected to reversed cyclic loading is presented in this investigation. The attempt has been made to demonstrate the influence of steel fibers reinforced self-compacting concrete (SCC). Three exterior beam-column joints having the same geometry were cast and tested through reversed cyclic load using displacement-controlled mechanism. All three specimens are designed adequately in accordance with IS 13920:2016 code. The hysteresis loop, ductility factor, stiffness degradation, energy dissipation characteristics, and damage propagation are considered to quantify the response of joint specimens. The results show enhanced ductility, energy dissipation capacity and damage tolerance behavior with the increase in steel fibers percentage in SCC.

Failure investigation studies on a large number of buildings exposed to earthquake loads revealed that Beam-Column Joint (BCJ) is the most critical structural regions in any moment resisting RC structure. The structural response of RC moment resting frame system under the earthquake loads mainly depends on the behavior and performance of the BCJ. It should be designed and detailed properly to ensure safety and serviceability of the structure under various earthquake loads. In the present Experimental work, Normal Strength Concrete (NSC) Fiber Reinforced Beam-Column Joint specimens are cast and are subjected to Cyclic loading. Proportions of steel fibers used are 0%, 0.5% and 1%. Load response curves have been plotted to demonstrate change in the Energy absorption, Stiffness Degradation and Ductility factors.
