Cable-stayed bridges chatter performance analysis

With the development of transport, compared with ordinary cable-stayed bridge cable-stayed bridge because of its convenience, appearance, economical characteristics of the construction, in the construction of roads, bridges in the city has been rapid application, but because of the structural rigidity of special bridge requirements, so now one of the few cablestayed bridges has been built.Part of the existing cable-stayed bridge features to summarize, found common ground stiffness, a large proportion of the live load, and by information found in the study of large-span cable-stayed bridge wind performance gap by almost belong.However, with the development of road transport services, more and more large-span, and with spans increase wind loads on the beam impact has become a non-negligible factor.Taking a cable-stayed bridge in the background, its research performance chatter, and the first use of ANSYS software and the numerical simulation of the effect of wind load stress analysis for the construction of the latter part provides a theoretical basis.
