Abstract:
Beam-column joints require a highly ductile design in the event of unexpected loadings that necessitates the need for ductile concrete in such vulnerable locations. Past studies indicate that the addition of shredded rubber to concrete improves its ductility significantly. Also, the incorporation of steel fibers enhances the ductile and engineering properties remarkably. Considering these aspects and congestion of reinforcement in the joints, a sustainable composite having improved ductility has been developed by adding scrap rubber to self-consolidating concrete (SCC) as a partial replacement of fine aggregate. The behavior of rubberized SCC beam-column joints under monotonic and cyclic loads has been studied. In addition, the effect of adding steel fibers to rubberized SCC has also been studied. The analysis results indicate that the combined use of rubber and steel fibers in SCC significantly enhances the load-carrying capacity and crack resistance of the specimens under monotonic and cyclic loads.
