ANALYSIS OF THE FALL-DOWN OF THE BRIDGE OVER THE HERNÁD AT GESZTELY

Abstract

In Hungary, several old trussed highway bridges of trough-type fell down because the vehicle passing through them was higher than permitted and got caught into the upper wind-bracing. The analysis shows that the trussed bridges where upper wind-bracing can be found only in the middle section of the bridge (the height of the trussed girder is varied) are liable to be destroyed by vehicles of a high load.
