Design and Construction of Sunyudo Pedestrian Bridge Using Ultra-High Performance Concrete, Ductal

초고강도 콘크리트 Ductal을 이용한 선유도연결 보행전용교량의 설계와 시공

This paper describes the design and construction of main Arch bridge using Ultra-high performance concrete, Ductal in the Sunyudo pedestrian bridge project. Ductal is a new family of cementing materials with remarkable properties. Its mechanical characteristics reach unique values, with compressive strength in industrial use of 180 to 230 MPa and bending tensile strength of 50 to 80 MPa. By the use of Ductal, main Arch bridge crossing the Han-river is designed to the span 120m-long with optimized $\pi$ shape section.
