Joint behavior of self compacting concrete using recycled concrete aggregate and hybrid steel fibers

Abstract

The beam column joint failure normally occurs due to the natural disaster like a strong earthquake, which leads to the collapse of buildings. A huge number of experimental studies have been conducted on beam-column joints made up of SCC using Natural aggregates. Only a few numbers of studies have been done on SCC (Self Compacting Concrete) made up of Recycled Concrete Aggregate (RCA). So, there is a necessity arises to conduct the experiments on beam-column joints produced with SCC using Recycled Concrete Aggregate (RCA). This paper presents behaviour of beam-column joint made up of SCC with RCA. A series of ten beam-column joints with three interior joints and two exterior joints were subjected to loading test, and the results were obtained in terms of load carrying capacity, ultimate load at failure and deformation curves. The obtained results gave experimental evidence of the applicability of RCA in SCC beam-column joints.
