ABSTRACT
An experimental investigation carried out on the reinforced concrete exterior beam-column joint was subjected to static load is reported in this paper. The objective of this study is to investigate the existing RC beam column joints which are designed as per BIS 456-2000,which must be strengthened, since they do not meet the requirement given in the ductility code IS 13920-1993 are inadequate and it needs to be upgraded regarding the detailing of reinforcements an attempt has been made to introduced an additional reinforcement called “core reinforcements” in the joint region to improve the reinforcement detailing pattern and strength behaviour to ensure good performance of the joint as well. The experimental study was conducted on full scale exterior beam column joint specimens detailed in three different categories such as IS 456-2000 as reference joint (RJ), IS: 13920:1993 as ductile joint (DJ) and core reinforcements as core joint (CJ) were casted and tested under static loading and the results were evaluated with respect to in terms of strength, ductility and stiffness degradation. Test results showed that the use of core reinforcement reduced the damages in the joint region and is one of the most effective techniques to improve the seismic resistance of RC structures.
