The real static behaviour of historic bridge in town Krásno nad Kysucou in Slovakia

Abstract

The paper is focused on real static behaviour of the oldest reinforced concrete arch bridge in middle Europe, which is located in the town Krásno nad Kysucou over the river Bystrica. This bridge was diagnosed and the task was to determine the load-carrying capacity of the bridge. Documentation of the object has not been available, so, it was not clear what the static schema of the bridge is – whether it is fixed arch or two-hinged arch and whether the spandrel walls located on the both sides in the longitudinal direction are cooperating with the arch. The paper is focused on the static calculation and the load-carrying capacity calculation in order to compare various static schemas.
