Measurements During the Testing of Steel Railway Bridges

The measurements conducted within the experimental investigation of steel railway bridges in Zorkovac (the bridge “Zorkovac”), Fužine (the bridge “Ličanka”) and Zagreb (the bridge “Sava”) are presented in this paper. On these bridges, there was static and dynamic testing conducted under traffic load. The strain in critical structural elements and vertical displacements of the bridges were measured within the scope of the static tests. Vertical displacements of all the mentioned objects were measured by means of a modified method of geometric levelling, however, on the bridge “Sava”, the displacements were also measured by means of a trigonometric levelling method. Furthermore, dynamic tests were conducted and modal parameters that are very important for future structural health monitoring were determined. Natural frequencies of the bridge “Sava” were determined by means of two methods, operational modal analysis and from vibrations measured by robotic total station. Experimentally determined vertical displacements, strains, natural frequencies and modal shapes are presented in this paper. Finally, this paper presents numerical models of bridges where measured values are compared with the calculated values.
