Manual Determination of Buckling Curve
Manual determination of a buckling curve
The image shows an input list for defining the buckling curve for the stability analysis. The entries include the options “Automatic,” “a0,” “a,” “b,” “c,” and “d,” with “b” selected. In addition, the columns “y/u-axis” and “z/v-axis” are displayed with the “Automatic” setting. According to EN 1993, the buckling curves a0, a, b, c, and d correspond to imperfection factors α ranging from 0.13 to 0.76 and describe the reduction factor χ as a function of the related slenderness ratio λ̄.
