Abstract

Abstract: In order to improve the accuracy of the stay cable force, and improve the uniformity of the single steel strand cable force, the existing formula for calculating cable force was revised and perfected, and a more accurate formula for calculating cable force was presented. The existing control method of single steel strand cable force was also revised and perfected, and a more accurate control formula and control method for cable force was presented. These studies were conducted according to the basic theory of equal tensile force method of parallel strand stayed-cable.

Key words: bridge engineering, parallel strand stayed-cable, equal tensile force method, control of cable force
