A State-of-the-Art Review on Strengthening Technique used for Existing Column with Steel Jacketing

This paper review a technique used for strengthening of existing columns with steel jacketing. Generally, steel jacketing is consisting of steel angle profile, steel plates/strips with different configurations. After Gorkha earthquake - 2015, thousands of people were killed and the buildings, infrastructures were damaged. After that earthquake, lots of building needed to be strengthening its capacities to meet the present code provision and to make them earthquake resistant building. In this paper, a non-destructive test of an existing reinforced concrete column will be first presented and after that both experimental and analytical investigations conducted by various researchers have been reviewed.
