Experimental Monitoring of a Bridge in Bratislava

Abstract

The New Bridge over the Danube in Bratislava represents an attractive steel cable-stayed bridge erected in the year 1972. The length is 431.8 m. The submitted paper deals with dynamic identification realized as the organic part of regular virtual monitoring on the bridge. It describes the methodology of experimental testing and brings some results of the dynamic loading test. During this test, it was observed that the dilatation unit on the right waterside showed some failure. Due to this failure, the dilatation unit acts as a generator of vibration of the end bridge span. Based on the experimental testing the failure was detected and the dilatation unit was renovated.
