ABSTRACT

Corrugated steel web composite box girder is widely used in bridge engineering because it can fundamentally solve the problem of cracking of box girder web. However, due to the complexity of corrugated steel web composite box girder structure, it is inconvenient for finite element modeling. How to refine the modeling and ensure the speed and efficiency of modeling has become a difficult problem in the process of modeling. In this paper, on the basis of summarizing various modeling methods, the idea of docking MIDAS FEA and MIDAS Civil software was put forward, and the method of finite element refinement model of corrugated steel web box Girder Bridge was discussed. Firstly, the model of concrete and internal prestressing tendons of composite box girder was established by MIDAS FEA software. After imprinting, the model was connected with MIDAS Civil, and the corrugated steel webs and external prestressing tendons were established in MIDAS Civil. Finally, the operation calculation was carried out.
