Kształtowanie ram portalowych z zastosowaniem połączeń śrubowych

The rational shaping of steel portal frames relies not only on suitable choice of the structural system, static schema or the type of sections, but also on the suitable solution of joints and their actual characteristics. In the paper, the influence of the strength and stiffness of the joints on redistribution of internal forces in the one-storey portal frame was presented. The procedure for calculation of the stiffness of the bolted splice joints was elaborated too.
