Abstract:Six two span continuous type beam-column specimens of span 1.75 m (5 ft.06.9 in.) each were tested to failure. The specimens had beam section of 150 x 250 m m (6 x 10 in.) and column section of 150 x 150 mm (6 x 6 in.). The beam section had 2 bars each of 12 mm (l/2 in.) diameter. two test specimens (Type A) were of reinforced concrete, having steel stirrups as shear reinforcement. In other two specimens (Type B) steel fiber reinforced concrete (SFRC), having steel fibers of size 25 x 0.25 mm (1.0 x 0.01 in.), 2% by weight of concrete was used throughout the specimens. In the remaining two specimens (Type C) SFRC was provided in the connection region only. An axial compressive load of 18000 kgf (40 kips) was applied to the column section by post tensioning high strength steel. Vertical load was applied to each of the beams at a distance of 1.175 m (46.26 in.) fran each end. Test results showed an increase of 19% and 9.9% in shear and moment capacities respectively of SFRC connections over that of RCC connections. SFRC connections failed in ductile mode of failure. SFRC was found to be very effective in the connection region in specimens tested for low cycle fatigue.
