Abstract
The geometric nonlinear large deflection analysis of structures comprising members of asymmetric thin-walled open section is investigated. The geometric stiffness matrix for a thin-walled element is derived, incorporating second order nonlinear strain terms in the governing energy equation. The derived stiffness matrices are used to predict bifurcation loads of a number of structures. An updated Lagrangian formulation, coupled with the numerical arc-length technique, is employed to trace the nonlinear pre-buckling and post-buckling load-deflection paths. Numerical examples of the large deflection behavior of an hexagonal frame and of eccentrically loaded and restrained unequal angle beam-columns are presented.
