Abstract A finite element method capable of predicting the buckling capacity of arbitrarily shaped thin-walled structural members under any general load and boundary conditions is presented. A rectangular thin plate element with 30 degrees of freedom is used. The linear and geometric stiffness matrices for this element are derived explicitly using symbolic manipulation, thereby eliminating the need for the expensive process of numerical integration. Further, the explicit form of the stiffness matrices makes it easier to interpret the physical significance of the various stiffness terms. For sections composed of rigid flanges and flexible web, a lower-order plate element is used in combination with a general beam-column element to form a super element for predicting distortional buckling modes. Formex formulation is used for the automatic generation of the data necessary for the analysis. Numerical examples of thin-walled structural members involving local, distortional and flexural-torsional buckling modes are presented to demonstrate the accuracy, efficiency and versatility of the method.
