| Abstract: | Taking Ningbo Daxie second bridge as an engineering background, this paper introduces the construction procedure of the derrick crane installing of steel box girders and uses the finite element analysis software ANSYS to establish simulation model of the steel box girder. In the period of cantilever construction of girder, the protection force of derrick crane and constant load are considered and analysis of stress state of steel box girder is conducted. Through the ANSYS finite element analysis, the stress distribution of the steel box girder is obtained so as to understand the loading mechanism of steel box girder during the construction stage, which is significant to guide practical engineering. |
