| Abstract: | In this paper, a method for computation of aerostatic stability of long span bridges, the nonlinear finite element method, is put forward. The method in question is based on the ANSYS program and has taken full account of influences of the structural geometric nonlinearity and aerostatic load nonlinearity. With the method, the Wuhan Yangluo Changjiang River Highway Bridge is computed and analyzed for example. |
