| Abstract: | Much attention is devoted to prestressed concrete continuous fish-bellied box-girder bridge for its advantages,such as attractive appearance,uniform stress,reasonable headroom,which makes it popular in the municipal engineering. The analysis and design method of the super-structure is introduced and stress distribution under different loads is presented. The research results can be a reference for similar bridge. |
