| Abstract: | Based on the object-oriented programming （OOP） technology, the CAD program which is used for optimizing calculation of the tendon in prestressed concrete continuous girder bridges is designed. By the FEM program, the structural internal force is calculated, and the data are fed back to the system for optimizing calculation. Then the mathematic optimizing model and solution for the tendon are generated, as well as the program is designed, in order to implement the optimizing calculation of the tendon amount. |
