Numerical simulation of a thin-walled beam with warping stiffeners undergoing torsion

Kreja I., Szymczak Cz.

TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk

Vol. 6, No 3

453-460

A new approach to numerical simulation of behavior of thin-walled beams of open cross-section with some warping stiffeners is presented. The structure model consists of one-dimensional finite elements described by the standard theory of thin-walled beams with non-deformable cross-section and FEM superelements with warping stiffeners. Comparative study of different kinds of modeling of the beams is performed; some numerical examples of simulation of I-beams behavior are given.
