On problem of stabilization of steel thin-walled beams in bending by sandwich panels

Original language description

Planar members such as sandwich panels have been widely used in building industry as roof or wall cladding. Besides covering of large spaces there is another significant feature of such members. When fastened to a supporting beam in bending or compression these members contribute to stabilization of such beam against buckling. It is particularly appreciable when a beam of a thin-walled cross-section is utilized. It involves purlins, wall substructure beams and others. The presence of planar members considerably increases buckling resistance of beams of slender thin-walled sections that are prone to buckling. There is number of factors influencing performance of these structural systems and stabilizing effect of planar members. Since these factors are mostly independent on each other and have a large dispersion, a pure mathematical solution of this problem is not practicable or even feasible. Influence of some factors on overall behavior may be efficiently assessed by experiments or numerical simulations. This paper focuses on investigation of behavior of steel beams of cold-formed thin-walled sections stabilized by sandwich panels fastened at the top flange of beams. Sandwich panels are specific structural members that consist of several layers of different material characteristics. They can work as simple or continuous members. This study particularly deals with influence of sandwich panel thickness and its effect on stabilization of steel beams. Geometrically nonlinear numerical analysis is conducted and substantial results are summarized and presented.
