Plate Buckling

Stiffened plate buckles in different modes, including web/flange buckling, torsional buckling, plate buckling, and interactions of them. Generally, interactions of different buckling modes in stiffened plates are ignored and elastic buckling analysis of each mode is treated separately. In some design codes, to cope with interactions of different buckling modes, the influence of adjacent elements are considered as rotational springs. The main aim of this study is to compare literature- and rule-based expressions to assess the elastic buckling strength of T-bar stiffened plates and to identify the applicability of selected expressions for certain conditions. Different buckling modes and their interactions are investigated, and critical Euler stresses are evaluated. Upon comparison with given expressions and the finite element method, it is found that some of the proposed expressions are not applicable in certain conditions.
