Abstrait: |
This paperhas been intended as an introduction to design example of 3-pylon cable-stayed bridge system applying Ultra High Performance Concrete (UHPC) with compressive strength of 180MPa and explanation of structural characteristics, benefits, and risksolutionscaused by applying UHPC. Steel composite and concretecable-stayed bridges werecheckedin order to comparewith UHPC cable-stayed bridge through the construction cost evaluation. The precast segmental method with launching truss was applied for activating the compressive strength of 180MPa. Stiffened girder needed various checks for ensured safety during construction. Lastly various types of section weretested for solving vibration problemsof edge girder with low height. The aerodynamic stability had been satisfied after the fairing and baffle set up on external edge girder and in the middle of edge girder, respectively. |
