Specifying Parameters for Automatic Determination of Imperfections
Specifying parameters for automatic determination of imperfections
The dialog box for defining a buckling mode contains the tabs “Main,” “Buckling Mode,” and “Assignment.” The settings for automatic determination specify 10 modes to be analyzed and the definition type “Relative.” The “Initial Bow” parameter is specified as e₀/L = 1/300,000. The graph shows the imperfection mode between nodes i and j over the length L with the horizontal deflection e₀, as well as the local axes x, y/z, and u/v.
