Abstract

The aim of this study is to make an analytical examination on how FRP tendons influence the mechanical behaviors of prestressed composite girders in both elastic and plastic regions, because there is still a necessity of providing an adequate amount of safety factor for structures using FRP materials. Furthermore, a method of the performance evaluations related to the load-carrying capacity and the deflection control of the prestressed composite girders with idealized FRP tendons is proposed based on the analytical results considered with some optimum parameters which are geometric parameters and material parameters. Finally, a design concept of the prestressed composite girder with FRP tendons is discussed in the construction of new bridges as well as in the bridge strengthening.
