| Abstract: | Based on Erqi Yangtze River Bridge,the steel-girder design of cable-stayed bridge was elab-orated briefly,which included comparative study of the cross section form,mixed girder,steel-con-crete joint section,constraint between tower and beam,and also included innovative design of open section hybrid composite steel girder structure,U limit at the middle tower.The study can provide reference to design the same type bridge for its economy,reasonable structure and convenient con-struction. |
