| Summary: |
| For designing unrestrained steel beams in accordance with EN 1993-1-1 it is
necessary to know the value of elastic critical lateral torsional buckling moment . The
aim of this paper is to present different methods for calculating elastic critical lateral
torsional buckling moment and analysed them. Methods proposed by Trahair, Clark and
Hill and Balaz and Kolekova are discussed and examined through numerical example.
The obtained results have shown no significant differences between analysed methods in
the case of simple beam under uniform distributed load and concentrated point load at
mid span. Further more detailed investigation is needed for more complex cases. |
