A Review on Seismic Retrofit of Beam-Column Joints

Earthquakes are one of the biggest life-threats in the world. The effect is immediate, with little to no warning about damage plans and the collapse of buildings/structures. Prevention of earthquake-related disasters has become more and more important in recent years. Preventing disasters involves reducing seismic risk by retrofitting existing buildings. Seismic retrofitting has now become a crucial issue. Retrofitting helps improve the structure's strength, resistivity and overall lifespan. Recent occurrences of earthquakes in various parts of the world have clearly shown the urgency of repairing deficient seismic structures. The paper summarised many past studies in the form of a seismic strengthening solution, based on the type of beam-column joints, retrofitting technology and fiber reinforced polymers (FRP).
