ON THE DYNAMICS OF SUSPENSION BRIDGE DECKS WITH WIND-INDUCED SECOND-ORDER EFFECTS GIANFRANCO PIANA DIPARTIMENTO DI INGEGNERIA STRUTTURALE E GEOTECNICA SAPIENZA UNIVERSITÀ DI ROMA Abstract. In numerical modelling of suspension bridges, a preliminary step for the aeroelastic stability analysis is the determination of natural frequencies and mode shapes of the structure. They are generally obtained by a modal analysis conducted with respect to the deformed configuration under permanent loads. In this talk, a simplified analytical model will be introduced to discuss the dependence of the natural frequencies of suspension bridges upon the steady aerodynamic loads. This will be obtained by including the second-order effects induced by a constant transverse wind in the linearized bridge equations of motion. Numerical results will be presented and implications in flutter analysis will be discussed. E-mail address: [email protected] 1
