Abstract

The paper deals with identifying the condition of bearings on a truss bridge with a reinforced concrete bridge deck by means of repeated dynamic tests. Interferometric radar was used to record the dynamic response of the bridge. This device measures the dynamic displacements of several points of the structure simultaneously. In addition to displacements, the values of eigenfrequencies in the vertical direction were also compared. The frequency values were also determined from acceleration records for purposes of comparison.
