Using inclined tensioned cables to balance the steel pipe arch rib during concreting;

Structural System of Partially Cable-Stayed Bridge and analyses of Cable-Force;

Based on the existing algorithm and through ascertaining the influence matrix of the tensile force in the construction of oblique pulling rope,the optimized stayed-buckle cable force is calculated at each stage of archrib hoisting phase of a model bridge during construction and the designed requirement is fulfilled through empty steel tube in falling state.
