STUDY OF SUPPORT LINKS INFLUENCE OF COMPOSITE BRIDGES ON THEIR FREE VIBRATION PARAMETERS

The paper proposes a rod finite – element model for the description of composite steel and concrete spans with link slabs. As an example of the transformation of the support links relations the effect of rigidity on the parameters of free vibrations of the spans according to scheme 2x42.1 m has been analyzed.

Keywords: temperature - uncut spans (TUSs), matching conditions, over pier links, free oscillations.
