CALCULATION METHOD FOR ADJUSTING THE LENGTH OF HANGERS DURING THE ERECTION OF SUSPENSION BRIDGES

During the construction of suspension bridges, it is required that the length of hangers be adjusted so as to eliminate the effects on the stiffening-girder erection caused by the construction errors of towers and main cables,and to guarantee the curve of stiffening-girder meets the design requirement for the completed bridge, when these errors exceed the tolerances. Thus,a practical approach of adjusting the length of hangers is proposed. in which the geometry and internal force for the completed bridge is obtained with an iterative procedure in which the whole erection process is divided into two stages and modeled by the geometric nonlinear finite element method. The implementation example shows that this approach is more precise.
