EXPERIMENTAL MODAL TESTING OF A CONCRETE BRIDGE

Mihai NEDELCU, Emil FRĂŢILĂ, Mihai ILIESCU

Abstract


This paper reports on the experimental analysis of a concrete bridge. Vibration problems generated by the resonance phenomenon are often encountered in bridges. Cases such as Tacoma Narrows, Washington, USA and Millennium Bridge, London, UK, are just two examples of structures that showed problems with resonance due to the exterior, dynamic actions. The concrete bridge whose dynamic response has been measured tends to vibrate excessively under car traffic.

Keywords: experimental modal analysis, resonance, vibrations, concrete bridge
