Abstract
The second part of the thesis on non-linear behaviour and stability of thin-walled elastic beams and columns of open cross-section is mainly concerned with description and interpretation of numerical results obtained by means of the methods described in the first part of the thesis. A number of beams and columns have been examined and the following conclusion have been established:
Consideration of the pre-buckling deformations, i.e. major axis curvatures, leads to an increase of the lateral buckling load which compared with the conventional lateral buckling load may be of considerable order of magnitude.
Only stable bifurcation points have been found for thin-walled beams of doubly symmetrical cross-sections (I and H profiles).
Mild imperfection sensitivity occurs for transversely loaded thin-walled beams of mono-symmetrical cross-section for a certain range of column lengths.
A number of ideas for relevant, future research within the field of thin-walled beams are given at the end of the second part of the thesis.
