Abstract

In this study, attention is mainly focused on the effect of the construction process for prestressing composite girder bridges with external cables. Then, the performance evaluation related to the load-carrying capacity and the deflection control of the prestressing composite girder is carried out based on the analytical results considered with the constructionprocess as well as some geometric parameters, for not only structural design of new prestressed composite girder bridges but also bridge strengthening of old ones. A design concept is discussed in the construction of new bridges based on a parametric study on the effects of the mechanical behaviors, and as an example of an actual application of the design concept, theproposed method are applied on an actual bridge and the results are obtained together with the performance evaluation.
