| Abstract: | Because of the increasing the span of cable-stayed bridge, aerostatics stability recently becomes more focusing both in design and construction. A technique to analyze the aerostatics stability for long-span cable-stayed bridge is proposed in the paper. We adopt the shape of a section, initial wind angle of attack, and other parameters as variabels.Ageneralized computof 1, 000 m is designed as an example for discussing. Some main parameters are obtained form the investigation. |
