Abstract: The finite shell-beam models for static and global stability analysis of thin-walled structures with open cross-section are proposed. The discretization using thin-walled beam elements is connected with the space discretization of some parts of the frame. The space joint element, formulated using only translational degrees of freedom on cross-sections connecting the joint with the thin-walled beams and the so-called transition elements, defined between the beam and the shell nodes are used for consistent coupling beams and shell parts
