| Abstract: | In order to investigate the nonlinear aerostatic behavior of long\|span bridges, an approach is described here, in which both the effects of nonlinear aerostatic loads and structural geometric nonlinearities are considered, and the computing procedure is also programmed. Finally with the Jiangyin Suspension Bridge over Yangtze River as an example, nonlinear aerostatic analysis is performed, the influence mechanism and the role of those effects in aerostatic behavior of long\|span bridges are clarified. |
