This report describes multi-hazard considerations in vibrations of longspan bridges with focus on seismic and wind action. Such bridges, being flexible structures, are inherently vulnerable to wind loads. However, some response parameters of such bridges, for example tower and deck acceleration, can be significant during large earthquakes which produce ground motions with low frequency content. To illustrate this problem, a case study of the Runyang Suspension Bridge (RSB) is used. A finite element model of the bridge is created and verified against published literature.
