SYSTEM DAMPING EFFECTS ON BENDING AEOLIAN OSCILLATIONS OF CABLE-STAYED GIRDER BRIDGES

In recent years, the system damping effects on wind-induced response of cable-stayed girder bridges have attracted attention. The authors previously defined a governing cause due to the so-called internal resonance, and reported that the system damping would have good effects on dynamic response to moving design live loads. In this paper, an analysis technique of times series response of bending aeolian oscillations is proposed taking into consideration the internal resonance. Furthermore, time series response analyses of an actual multi-cable-stayed bridge are performed from the viewpoints of dynamic safety. Finally, the authors attempt to obtain data on the application to design for wind resistant stability.
