SPATIAL STABILITY OF NONSYMMETRIC THIN-WALLED CURVED BEAMS. II: NUMERICAL APPROACH
In a companion paper, for spatial stability of nonsymmetric thin-walled curved beams, a general formulation was derived based on a displacement field considering the second-order terms of semitangential rotations. Closed-form solutions were newly derived for in-plane and out-of-plane buckling of simply supported curved beams with monosymmetric sections subjected to pure bending or uniform compression. This paper, to get numerical solutions for the buckling of thin-walled curved beams subjected to general loadings, develops finite-element procedures using thin-walled curved beam elements and straight frame elements with nonsymmetric sections. It presents numerical examples for the spatial buckling of doubly symmetric, monosymmetric, and nonsymmetric thin-walled circular beams and compares them with previously published solutions to illustrate the accuracy and the practical usefulness of the analytical solutions and numerical procedures.
