heal.abstract This paper deals with the parametric resonance of steel bridges pylons due to time-depended traffic loads. The analysis follows the basic lines of Bolotin's technique for the solution of nonlinear problems of dynamic instability. In this work, the cases of forced vibrating pylons with and without damping subjected to periodic external dynamic forces acting axially are investigated. The effect of bridge vibration due to traffic loads has been also taken into account. Through the aforementioned technique, useful results regarding the dynamic stability of pylons are obtained, and illustrative examples for various cases of geometry and loading are presented in the form of plots and diagrams. © 2012 Springer-Verlag. en
