    Abstract
  • In order to accurately obtain the cable forces of anchor-span strands for suspension bridges to easily control the cable forces in construction course, a refinement model was established using nonlinear analysis software BNLAS and based on identified parameters of anchor-span strands of Taizhou Yangtze River bridge. A series of cable force-frequency data was obtained by assigning different initial cable forces of cable strands in the model. The explicit expression of cable force-frequency relationship was obtained by the regression analysis of the data to give a method of cable force calculation and avoid solving a transcendental equation by iteration to gain the cable forces. Based on elasticity theory calculation, a measure of cable force adjustment was put forward, that is cable force adjustment is transformed into screw pitch adjustment. The research results show that the method of cable force calculation has an error of less than 3%, and the measure of cable force adjustment is reliable and can meet the need of cable force control during the construction.
