Fundamental study on the simplified analytical method of PC bridges

Abstract

In this study, a model was proposed in order to estimate initial stresses such as a stress at the erection of a PC bridge. A simplified analytical model was applied and the modelling was confirmed by investigation of stiffness of the lattice members. Although the model was simple and of practical use, analysis of a PC box girder bridge gave results of the initial stresses with standard accuracy. Also the applicability and problems when using the proposed model in design were shown.
