Structural Behaviors of Large Span Prestressed PC Bridge Stiffened by CFST Arch

Abstract

High-speed railway system has been developed with unprecedented pace in recent decades. Various type of bridges (elevated structures) were built for high speed railway infrastructure due to land saving and sound operational condition provided. In this paper, the detailed modeling of the prestressed concrete girder stiffened by concrete filled steel tubular (CFST) arch was developed. Displacement, static stress, dynamic characteristics was obtained by analysis. The overall structural performance has been concluded.
