AbstractA previous paper presented a method of analysis for any open unbranched thin-walled section considering both rigid body movement and cross-section distortion (including local buckling). It described briefly the calculation procedures required in order to obtain section properties related to each of a number of cross-section distortion modes. These properties were generally calculated using first-order theory.This paper describes in full how second-order theory can be used to calculate the section properties for all modes, including each of the four rigid body modes. In the process of developing the second-order generalized beam theory, additional section properties evolve which enable the first-order equilibrium equation to be modified to consider second-order elastic critical load problems.
