Abstract
Suspension bridges are the current technical solution to overcome long distances. In this paper, the traditional suspension scheme is compared with a different technical solution providing additional structural resources thanks to a system of cables with opposed curvature. Favorable effects of this scheme are evidenced, concerning wind resistance, regarding to serviceability conditions. Dynamic analyses in time domain are performed, within a FE framework capable to take into account structural nonlinearities and dynamic wind loads.
