Abstract
It is a difficult technical problem to make sure that the curve of girder segments without han-gers is transitioned smoothly and the system transformation is successful and that the internal force keeps consistent with the girder curve when connecting the segments near the tower rigidly and transferring structure system for the suspension bridge with three-span continuous stiffening girder. The system transformation methods at home and abroad of girder segments without hangers are discussed in this paper, and by taking a suspension bridge of over 1 000 m with three-span continuous stiffening girder as an example, the system transformation, curve adjustment and construction control of the girder segments without hangers are realized.
