| Abstract: | This paper takes steel-prestressed concrete mixed continuous box girder bridge-318 State Road Longbridge Bridge as an engineering example to study the parameter of the length of the steel box based on the mode of connection between steel box and concrete girder.By making use of large common bridge design software,the real bridge can be modeled.Then numerical simulation analysis focuses on the characteristic of bending moment,shear force in the dead/live load condition under the change of the length of steel box to demonstrate the inflection point position under the change of the length of steel box parameter.Finally the related conclusions are reached for design and research of steel-prestressed concrete mixed continuous box girder bridges. |
