All-composite superstructures for accelerated bridge construction

Abstract: This chapter presents the design, manufacture, installation, and in-service structural performance of an all-composite sandwich bridge superstructure for accelerated bridge construction (ABC). The superstructure is made of fiber-reinforced polymer (FRP). The discussions about the manufacture and installation include construction details when the FRP superstructure is implemented in practice. The assessment of the in-service structural performance may provide baseline data for the capacity rating and serve as part of the long-term performance monitoring of the FRP superstructure. Finally, this chapter explains why all-composite superstructures for ABC can be economically competitive in the future.
