A critical review on behaviour of cold formed steel encased hot rolled steel sections
An emerging technique in the market today is the retrofitting of Hot Rolled Steel (HRS) sections by encasing Cold-Formed Steel (CFS) sections. The high strength-to-weight ratio of CFS (Cold-Formed Steel) sections makes them perfect for lightweight and quick-build structures. This paper introduces a comprehensive overview on the state of art regarding researches conducted on retrofitting of HRS sections and flexural behaviour of CFS encased HRS sections. Many steel structures are vulnerable to failure during unexpected load variations applied to the structure. Consequently, the most efficient and economic retrofitting system needs to be figured out and implemented. It is found the retrofitting of HRS sections by encasing them with CFS sections transforms the open configuration into a closed box type. Thereby enhancing the resistance of the built-up section against lateral-torsional buckling. By spreading stresses throughout the section and boosting the moment of inertia, the addition of CFS sections to an existing HRS section raises its section modulus and moment capacity. This enhances the section’s flexural strength and stiffness.
