摘要: The calculation of warping constant (C-w) for an open thin-walled open section is a tedious and difficult task and thus presenting an obstacle to routine design. Although C-w formulas and values for selective cold-formed steel sections are available in the AISI design manuals, most practicing engineers have limited idea of evaluating the warping constants for sections not listed in the AISI design manuals. This paper proposes a detailed step-by-step numerical procedure for evaluating the warping constant of a general open thin-walled section. Comparison shows virtually no difference between the calculated values and those listed in the AISI design manuals. The proposed procedure is a reliable and useful tool for computing the warping constant for an arbitrary cold-formed steel open section, which does not need a sophisticated computer software.
