This paper deals with a class of free vibrations for a two-span, two-lane steel-concrete bridge. The deck structure is modelled as a thin, homogeneous, orthotropic plate stiffened by beams running along the longitudinal direction of the bridge. The method of separation of variables is used to find exact solutions for a class of free vibrations of the structure. A comparison between analytical and experimental natural frequencies and vibration modes of the bridge is presented and discussed.

Abstract
This paper deals with a class of free vibrations for a two-span, two-lane steel-concrete bridge. The deck structure is modelled as a thin, homogeneous, orthotropic plate stiffened by beams running along the longitudinal direction of the bridge. The method of separation of variables is used to find exact solutions for a class of free vibrations of the structure. A comparison between analytical and experimental natural frequencies and vibration modes of the bridge is presented and discussed.File in questo prodotto:
