Diagnostyka systemów podwieszeń mostów
Artykuł opisuje badania dynamiczne przeprowadzone na systemie podwieszenia mostu Rędzińskiego we Wrocławiu przez międzynarodowy zespół naukowy w ramach projektu Narodowej Agencji Wymiany Akademickiej (NAWA).
The stay cable system of the Rędziński Bridge in Wrocław was the subject of dynamic testing carried out in 2019 by a 6-person international scientific team as a part of a bilateral exchange of scientists between the Republic of Poland and the Portuguese Republic. The testing was conducted within the project “Dynamic monitoring of bridge structures”, funded by the Polish National Agency for Academic Exchange (NAWA) and the Fundacao para a Ciencia e a Tecnologia (FCT) in Portugal. In this paper, the results of measurements carried out by the Polish team are presented. Dynamic measurements and the Structural Health Monitoring system of the bridge were used for the purpose of this study. The aim of the analysis was to determine the tension forces of the stay cables by using the indirect method of measurements and to compare the results with the data directly imported from the bridge monitoring system. 20 monitored stay cables were selected for dynamic investigation. In general, the values of tension forces determined by dynamic methods were higher than those derived from the monitoring system. This may be connected with the necessity to calibrate the force sensors installed in the stay cables. Some of the force sensors in the SHM system are inactive (no measurement data available) and need to be replaced.
