A State-Of-The-Art Review on Retrofitting Beam-Column Joint Using GFRP with NSM Technique under Seismic

Abstract—Recent development of seismic action has highlighted the consequences of poor performance of beam-column joints, which has been identified as the main principle cause of failure when the frame is subjected to earthquake loading. This paper summarized numerous past studies according to the type of beam-column joint, retrofitting techniques and fiber reinforced polymer (FRP). For this purposes, 100 research works from previous researchers were collected. The structural behavior of beam-column joint has been extensively studied in the past decades. Experimental and analytical solutions have been conducted and proposed by many researchers to understand the behavior of the beam-column joint. However, Near Surface Mounted (NSM) technique using Glass Fiber Reinforced Polymer (GFRP) in retrofitting beam-column joint has yet to be investigated. Therefore, this study is proposed for future research. In-depth investigations must be carried out as to gain more thorough understanding on the behavior of retrofitted beam-column joint using GFRP with NSM technique.
