Economic Study of Cold-Formed Steel Sections With Rectangular Hollow Flanges In Comparison With Hot- Rolled Steel Sections

الملخص

Recently, the use of cold-formed steel sections in the work of steel structures has been widespread because these sections have high strength to weight ratio. Cold- formed steel sections are characterized by Hot-rolled steel sections with an increase in strength to their weight. Therefore, the total weight of the structures can be reduced, and thus reduces cost. Cold-formed steel sections can also be easily manufactured according to the shapes and sizes structural requirement. [1]

This search aim to know the economic advantages of cold-formed steel section by conducting comparison between cold-formed rectangular hollow flang beam steel section (RHFB) with the commonly used hot rolled beam steel section. Both sections are having same weight of steel.

ANSYS 16.1, has been used to calculate section moment capacity for both beams and comparison has been made.
