Structural Optimization of Prestessed Concrete Continuous Box Girder Bridges in Highway Viaduct
According to using status of short span concrete bridges commonly used in highway viaduct, structural finite element analysis taking account of some parameters like connection between pier and beam, pier height, transverse bearing spacing and early support differential settlements was given based on existing cracking beams of small box girders during construction and operation. Some structural optimization recommendations and construction control suggestions was proposed. The study results are constant well with the data of the survey results and the actual status of projects, which may be taken as reference for similar projects in the design and construction.
