Unified Calculation of the Super and Substructure of a Bridge with the Rigid-Jointed Pier Top

When the pier top of a bridge or the rigid-framed structure is under the action of a loading, its superstructure and substructure will be Subject to the force and be deformed simultaneously. In this paper, the elastic resisting force of the earth to the foundation is considered and the stiffness coefficients of the pier top are obtained. The internal forces and the deformations of the bridge and the foundation are accurately analysed. A unified calculation is given to both the super-and sub-structure of the bridge.
