Abstract

Structural steel has become the best alternative for concrete in present construction industry. Hot Rolled steel Sections (HRS) available in market have standard shapes and sizes where as Cold Formed steel Sections (CFS) are produced in various shapes and sizes as per the needs of customer. A comparative study of cold formed sections and hot rolled section with respect to its axial load carrying capacityas a column is attempted. Hot rolled I-Sections and I-Sections formed by assembly of two cold formed channel sections are undertaken for the study. Columns with two end conditions i.e., both ends fixed, one end fixed and other end hinged of unsupported length 3 and 4 m are considered in the analysis. The safety index ‘β’ by reliability analysis is evaluated for cold formed sections.
