    Abstract
  • The finite element software ABAQUS was used to analyze the influence on the k value of the elastic distortional buckling stability coefficient considering changing of the type of opening, the size and the position of opening in the paper. The results showed that the position of the opening would affect the buckling mode of members, there was a safe distance between the openings, and the buckling stability coefficient k of the members with circle or slotted opening in web had different degrees of reduction. Finally, according to the main influencing parameters, the limits of end distance and distance between the opening were presented, some relative simple formulas were proposed to calculate the distortional buckling stability coefficient of cold-formed thin-walled lipped channel steel members with circle or slotted opening in web.
