Reinforcement of concrete columns using polymer jackets

Reinforced concrete structures suffer from various damage during their lifetime. Damage to structures can be caused by earthquakes, corrosion, fire, etc. Therefore, the need to repair and reinforce members of reinforced concrete over time is likely. Nowadays, FRP materials are used in this regard due to their unique properties. Reinforced concrete pillars can be strengthened as a key component of any concrete structure in a variety of ways, such as a full screw or FRP jacket. Thus, by creating a double enclosure, it can increase the column s performance, including its resistance and bearing capacity.
