Numerical and experimental investigation of hollow steel columns strengthened with carbon fiber reinforced polymer

In this research the hollow steel columns that strengthened with CFRP under axial compression has been investigated.Retrofit methods such as the use of steel plates increases the structural weight and in some cases using such method is difficult and impossible. This paper reports experimental and nu...
