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 consis-tent 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.关键词
