Sekundarni naslov:	Influence of transverse stiffeners on plate girder behaviour
Sekundarni povzetek:	The thesis deals with the resistance of plated girders composed of compact flanges and slender webs, which are usualy stiffened with longitudinal and transversal stiffeners in order to increase their capacity. Thin plated girders do not loose capacity due to the local buckling, as it happens in the case of column buckling, but they develop significant post-critical resistance after the elastic critical stress has been exceeded. A large parametric study was conduced in order to explain the effects of the transverse stiffener stiffness on the behaviour of plated girders. The transverse stiffener has to provide a rigid support to the plate, which assures the development of full post-critical shear resistance. The pourpose of numerical simulations in Abaqus was to find the second moment of inertia, providing a sufficent stiffness of the stiffener and to find out how various geometrical parameters affect the behaviour of the stiffener and resistance of the panel. Results of numerical simulations were compared with the requirements from standards SIST EN 1993-1-5 and AASHTO. The studies have shown that the SIST EN 1993-1-5 design rule based on the axial force turns out to be conservative. Based on numerical results a new design rule for intermediate transverse stiffeners is proposed. The new rule provides a necessary second moment of inertia of the stiffener which fulfills the stress and strain requirements for rigid transverse stiffeners.
