| Abstract: | Diagonal cracks in web on box girder is a kind of common disease occurring in prestressed concrete structure. Therefore, the technique should be controlled strictly, the upper pre-stress should be reduced, and the anti-shearing capacity of structures should be ensured in construction so as to prevent cracks occurring. |

| Keywords: | continuous rigid frame bridge warp in design warp in construction cracks in web |
