The responses of self-anchored suspension bridges to aerostatic wind

ABSTRACT: This paper uses an improved incremental iteration nonlinear method to analyze the nonlinear response to aerostatic wind of self-anchored suspension bridges. By subjecting the Jinzhou Straight Bridge to aerostatic loads, the bridge was analyzed to investigate the effect of factors such as initial wind attack angle, the cable sectioning, added wind attack angle and the wind speed cross-section parameter on the aerostatic displacement of the tower.
