What is Steel Jacketing for Column Retrofitting about?

The document discusses retrofitting existing reinforced concrete columns with steel jacketing to improve their load capacity and ductility. It describes an experimental study where 12 column specimens were tested - some were base columns, some were confined with 1mm steel jackets, and some with 1.6mm jackets. The results showed that steel jacketing more than doubled or tripled the compressive strength of the columns compared to unretrofitted columns. Failure of retrofitted columns occurred due to local buck
