The Applicability Study on the FRP-Concrete Composite Bridge Deck for Cable-Stayed Bridges

Abstract:

This study is related to the FRP-concrete composite bridge deck for cable-stayed bridges developed by the Korea Institute of Construction Technology since 2007. This deck disposes a FRP panel at the bottom and is orthotropic owing to its fabrication through pultrusion process. In the cable-stayed bridge applying precast deck, support conditions occur at the cross beam and edge girder. Therefore, need is to verify the performances in the longitudinal and transverse directions when applying the orthotropic deck to cable-stayed bridges. Accordingly, specimens enabling to verify the performance in each direction are fabricated and subject to structural performance test. Based on the test results, the serviceability and applicability of the FRP-concrete composite deck to cable-stayed bridges are evaluated.
