Dynamic measurements of two steel truss bridges for Structural Health Monitoring (SHM) were performed. The investigated bridges were: a single supported one span truss bridge and a multi-span truss bridge. Two possibilities of measuring setup were considered. A simple arrangement made up of one polygon has been used for data acquisition of the single span truss bridge. A more complex measuring setup made up of two polygons with up to 32 channels has been used for the large bridge with an entire length reaching up to 500 m. A connection of both measuring polygons was achieved by Wi-Fi antennas. The reason why the multi-span truss bridge was chosen for SHM is that the construction is nowadays overloaded. The dynamic measurements were done, ambient and semi-ambient data were analysed. After that, some mode-shapes were identified from the acquired data and then the data were compared with numerical calculations. Finally, experiences and conclusions from the ambient data measurement are summarized.

This paper deals with dynamic tests of the building with diesel generator and the process of determining the cause of the cracks in its walls. After initial measurements and FEM analysis, it was assumed that vibrations propagate to the structure through the base of the generator. Therefore, it was recommended to apply an elastic antivibration layer at the supporting base of the generator. However, the problem with cracks persisted and it was necessary to perform additional tests and analysis. Finally, acoustic simulation was performed and provided promising results.

“…Suitability of strain gauges for monitoring of steel railway bridges was confirmed in [5] and there are several case studies of SHM on bridges, where the strain was measured on different structural elements [6][7][8][9]. The work was also based on past experiences with test and measurements of various bridges [10,11].…”

Structural health monitoring (SHM) can provide information needed to make important decisions regarding the maintenance of bridge structures. However, the data collected from monitoring needs to be first translated into actionable, quantitative or qualitative based characteristics, that indicate the condition of a bridge. This paper presents a process of evaluation of such performance indicator in case of a steel railway bridge using the updated FE model and in-situ measurements of strains on selected stringers and floorbeams.
