Finite Element Program Design of Bridge Structures with Internal and External Prestressing
Recently internal and external prestressing enjoys a booming in the bridge construction, but the existing structural analysis programs of bridge can’t meet the requirements of analyzing the internal and external prestressing comprehensively. This paper will simulate internal and external prestressing effects by the finite element method; come up with some programming methods based on the object-oriented thought; and put forward the design and implementation methods of internal and external prestressing effect class by abstracting them to the corresponding class and elaborating the main features of each class, including the instantiation object and the typical method, to realizing the internal and external prestressing effects calculating. All of these will provide some references to the development of structural analysis program of bridge.
