Abstract

A new type of bridge superstructures referred to as Steel-confined Prestressed Concrete Girder (SCP Girder) was developed, which is composed of concrete, steel plate, and prestressing tendon. The girder may maximize structural advantages of these components : thus, long span bridges with low height girder may be constructed. For the effective design and fabrication of the girder, the design software program was developed and the process of fabrication established. The experimental girder designed using the program was manufactured in actual size to confirm the fabric ability of the girder. Propriety of design, structural safety, and applicability of the girder were verified through the load test.
