| Abstract: | Based on cooperative structural system and several important design parameter,a research of continuous span single pylon cable stayed bridge cooperative system is done for bridge tower,girder and cable force resistance-displacement characteristic.The analysis was done for main girder unsupported span,depth-span ratio of girder,main-side span ratio,pylon height to girder span ratio,etc.to see how the changes in design parameter will affect the structure.At last a reasonable value range is proposed. |
