A development for the new structural system having a superior wind resistance performance may be the alternative way for ensuring wind stability. The cable stayed-suspension bridge is one of alternative structural types. In this study, a parametric analysis was performed to examine static and dynamic behaviour of the cable stayed-suspension bridge according to variation of girder length supported by stay cable. The analytical result shows that the reasonable span ratio of stayed span over main span (stayed + suspended span) is between the range of 0.25~0.30. Also, structural performance of the cable stayed-suspension bridge with the span ratio of 0.25~0.30 is improved by more than 50% in comparison with a conventional suspension bridge. This improvement can lead to the reduction for the steel quantity of cable and stiffening girder and the size of anchorage. |
