Abstract: Forced vibration responses of nonlinear systems contain harmonics of the excitation frequency. These harmonics are either directly forced or are subharmonic, superharmonic, or combination resonances. ...

Abstract: This study presents a methodology for estimating stay cable tensions of cable-stayed bridges using genetic algorithm (GA) and particle swarm optimization (PSO). At first, a comprehensive cable model was used to represent ...

Abstract: In this paper, a vibration-based approach for estimating the cable tension forces in cable-stayed bridges is detailed and applied to the ambient response of the Veterans’ Glass City Skyway Bridge. First, the frequency ...
