The calculation of cable tension optimization for the cable stayed bridge in a reasonable state is an important step in the structure design and analysis of cable stayed bridge. This paper describes the application of feasible domain method in cable force optimization algorithm, and uses the results of MATLAB software programming to achieve the cable force optimization. Referring to a cable stayed bridge＇s cable force optimization example, and comparing the feasible domain algorithm results with a general optimization calculation results, the calculation results of the two methods are very close. The results show that the feasible domain algorithm applied to the cable force optimization results is effective and practical.
