| \ In this paper, a concept of optimization of cable prestresses of cable stayed bridges is firstly introduced. Secondly, by means of general influence matrix, a practical optimization method of cable prestresses of cable stayed bridges is developed. The method can not only be applied to determine the optimum cable prestresses of the bridges, but can also be used to construction control. The method used in programming is proved to be efficient and easy to realize. Finally, engineering applications of the method is presented. |
