RADAR INTERFEROMETRY TESTS OF THE BRIDGE RESPONSE DURING FULL TRAFFIC

Abstract

: This paper is devoted to measuring and evaluating displacements of the Prístavný most in Bratislava, Slovakia. It is a combined four-span highway and railway bridge with a length of 460.8 m. It is important to have knowledge of the functioning of the observed structure. Without a thorough and detailed numerical analysis, it is very difficult to correctly evaluate all measured data. Without detailed calibrated numerical models, in some cases it would not be possible to verify response of the structures. By comparing the numerical calculations and the measured data, we have the possibility to detect some structural defects that may not be visible. At the same time, we were be able to verify the impact of some non-structural elements of the structure on its behavior.
