DETERMINING THE RATIONAL COMPLETION CABLE FORCE OF CABLE-STAYED BRIDGES BY AN OPTIMIZATION METHOD
Cable-stayed bridge is a high-order hyper-static structure. The size of cable force affects the stress of the structure greatly. The key problem to determine the rational completion status of cable-stayed bridges is how to control cable force on completion status. Surrounding this problem, domestic and foreign experts and scholar have done a lot of favorable work and obtained much achievement. On the basis of comprehensive reading domestic and foreign relative documents, the author of this article classify rationally the current researching achievement, comments and compares advantages and disadvantages of each method and provide the principle and step of synthesizing rigid cable method and self-adjusting cable method to determine the rational completion cable forces, testifying the conception of the method is distinct and calculation is convenience and the result is rational.
