| Abstract: | In this paper, influence matrix methed of cable tension optimization for cable - stayed bridges is developed. In the methed, various object functions for the optimization of the bridge are uniformly expressed by cable tensions and influence matrixed in the concept of general influence matrix. The methed can not only be applied to determine the optimun cable tensions in reasonable stae of the bridge, but also be used to optimize the bridge during construction and on completion. The methed used in programming is proved to be efficient and easy to realize. |
