| Abstract: |
This study intends to explain the design and construction of the prestressed concrete(PSC) box- girders used for Incheon Bridge Viaduct. The superstructure of the Viaduct was planned and designed to be built with PSC box-girders, which consists structurally continuous 5 spans. Total 336 box-girder elements, each one is 15.7m wide, 50m long, 3m high, and weighing about 1,360 tons, were made by the pre-tensioned prestressing method at a specially built casting factory, transported to the construction site at sea, and erected by the FSLM(Full Span Launching Method), using specially developed methods and equipments. The details of prestressing tendons/bars and reinforcement were designed according to the AASHTO LRFD Bridge Design Specifications. In this paper, the major design items of PSC box-girders as well as related brief construction methods and sequences are introduced. |
