| Abstract: | The main span of the Shibanpo bridge is made up of steel-box girder and prestressed concrete-box girder. In the light of the complexity of local stress conditions at deck of the steel-box girder, the ANSYS software is used to establish the finite element space model of steel-box girder, and the characteristics of local stress distribution at deck of steel-box girder are analyzed. |

| Keywords: | continuous rigid frame steel-box girder vehicle load local stress finite element |
