REVIEW ON THE METHODS OF REINFORCEMENT TECHNIQUE IN REINFORCED CONCRETE BEAM-COLUMN JOINT

The awareness on seismic design for reinforced cement concrete (RCC) beamcolumn (BC) joint was started with publication of ACI-ASCE 352 report in 1976. In past earthquakes, several RCC buildings were suffered by severe damages/collapses. These failures were occurred due to the usage of poor detailing in joint and insufficient anchorage of beam longitudinal bars. The research on the BC joint was started in 1967 and extensive research has been carried out on studying the behaviour of RCC joints under seismic condition through experimental and analytical studies. There are different methods of reinforcing techniques have been developed over the years and their main aim was to determine the effective reinforcing technique for beam-column joint which include easy to adopt, effective performance, economical and cost-effective. This paper gives an overview of the use of different reinforcing techniques used in beam-column joint so far. The objective of this paper is to critically review the different techniques developed so far with reference to the effect of each technique and outlined the salient features of each technique.
