| Abstrait: |
Development of long-span railway cable-stayed bridges in China was systematically concluded including breakthrough of main span and technical innovations. Parametric analysis on Hutong Bridge, a rail-cum-road cable-stayed bridge with main span of 1092m, includes effects of side to mid-span ratio, girder height to mid-span ratio, girder width to mid-span ratio, and effective pylon height to mid-span ratio. Results show that structural rigidity decreases gradually as side to mid- span ratio increases. Increasing girder height improves the structural rigidity limitedly. Girder width influences natural frequency and flutter stability. Increasing effective pylon height could improve the whole vertical rigidity, and reduce the longitudinal rigidity of the pylon. |
