Based on the Minimal Stress Method for the Determination of the Reasonable Completed Bridge Cable Force

The cable-stayed bridge is a type of the bridges that can utilize the material properties fully and rationally.They are most favored by designers both at home and abroad with its good economic performance and crossover capability. we use the method of the minimal stress with constraints to optimize the cable force of the completed bridge under dead loads. In this way, we can attain the goal of reducing the project cost.
