FINITE ELEMENT ANALYSIS OF TORSIONAL-FLEXURAL BEHAVIOUR OF THIN-WALLED FRAME CONSIDERING JOINT WARPING CONDITIONS
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.
