墩顶固结桥梁上下部结构的联合计算

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

对于墩顶固结桥梁或其他刚架结构物,在荷载作用下,上下部结构将共同受力、共同变形.本文在对这类结构的计算中计入了土对基础的弹性抗力后求得墩顶刚度系数,准确地求出上下部结构的内力与变形,进行上下部结构的联合计算.

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.
