The Finite-Element Method Applied to the Deformation Analysis of Thin-Walled Columns

Summary

The paper presents the results obtained from computations of the deformations of thin-walled box-type column structures when subjected to both torsional and bending loads. The computed results, which correspond to various finite-element representations of the columns, are compared with experimentally derived values and with calculations based on closed form analytical expressions.

The accuracy of the computed static deformations depends on the specific nature of the finite-element model adopted. The results presented in the paper indicate the degree to which the resulting accuracy increases as the finite-element model becomes more refined. Some considerations regarding computing costs are also explained.
