Frames composed of thin-walled beam elements are frequently used as load-carrying systems in engineering practice. In this work the influence of different structural joint types on torsional moment transmission from column to beam is analysed. Two types of beam cross sections are considered, the I-beam cross section and the channel one. Four different structural joints are examined for both cross sectional types. Numerical simulations are undertaken using MSC. Nastran’s shell model consisting of eight-nodded flat elements. The results obtained are discussed through the test problems.

Paper deals with finite element buckling analysis of shear deformable beam-type structures. Displacements and rotations are allowed to be large but strains are assumed to be small. The corresponding equilibrium equations are formulated in the framework of co- rotational description, using the virtual work principle. Displacements and rotations are allowed to be large while strains are assumed to be small. Linear shape functions are used for the axial displacement, while cubic shape functions are employed for transverse displacements and angle of twist. The algorithm is validated on test examples.
