Abstract
Operational Modal Analysis aims at determination of natural frequency values, damping ratio values and mode shapes of an engineering structure in its operational conditions. The paper presents technique of modal testing of the bridge in its operational conditions with use of wireless sensors. The main goal of the carried out investigations was determination of natural frequencies and mode shapes of the bridge. The results achieved basing on measurement conducted with use of typical piezoelectric accelerometers connected to the measuring device with cable were compared with the ones determined basing on measurement with use of the wireless sensors.
