Numerical Evaluation on Warping Constants of General cold-Formed Steel Open Sections
Dung M. Lue,Jui-Ling Liu,Ching-Hau Lin 한국강구조학회 2007 International Journal of Steel Structures Vol.7 No.4
The calculation of warping constant (Cw) for an open thin-walled open section is a tedious and dificult task and thuspresenting an obstacle to routine design. Although Cw formulas and values for selective cold-formed steel sections are availablein the AISI design manuals, most practicing engineers have limited idea of evaluating the warping constants for sections notlisted in the AISI design manuals. This paper proposes a detailed step-by-step numerical procedure for evaluating the warpingconstant of a general open thin-waled section. Comparison shows virtualy no diference between the calculated values andthose listed in the AISI design manuals. The proposed procedure is a reliable and useful tool for computing the warping
