| Abstract: | Increment iteration method was used for analyze and calculate nonlinear aerostatic stability of large span cable stayed bridges with consideration of calm load nonlinear impact as well as geometrical nonlinear impact, and corresponding calculation program was developed. The feasibility of this method was verified through a cable-stayed bridge with main span being 1,000m. Discussions were carried out over the impact of such elements as calm load nonlinear and initial angle of attack on unstability critical velocity of large span cable-stayed bridges with calm. |
