| Abstract: | The critical wind speed of the aerostatic instability of long-span bridges may be less than that of the aerodynamic instability,Based on the discussion of the existing nonlinear aerostatic instability analysis,a composite criterion for judgment of aerostatic instability was presented according to structure characteristics the of cable-stayed bridges.With consideration of effects of geometric nonlinearity and the aerostatic load nonlinearity,the aerostatic instability of a long-span cable-stayed bridge was a... |
