The capacity of existing columns needs to be increased when there is an increase in applied load beyond the design load. Retrofitting is considered as more economic and time consuming technique as compared to reconstruction. This paper deals with the most advanced technique of retrofitting existing RC square column using stainless steel wire mesh (SSWM). It is found that the stress concentration at the corners of square column is relatively high and this reduces the efficiency of the SSWM wrapping. Therefore, the cross section of the column is converted from square to circular in order to increase the efficiency of the SSWM wrapping. This is achieved by attaching four D-section concrete covers at the four sides of the square column using a SikaHibond, Sikadur 30 LP binder. The circular column is then wrapped with a layer of SSWM whose wire thickness is 0.27mm. SSWM is chosen over carbon fibre reinforced polymer (CFRP) and glass fibre reinforced polymer (GFRP) in spite of their high tensile strength as their strength can't be utilised fully due to de-bonding problem. SSWM rather increases the strength, stiffness and ductility of the strengthened column.
