Finite element comparative analysis of two doorframe structures in container crane

In this paper, we build two according 3D finite element models of the container crane by ANSYS respectively based on two common doorframe structures of compound type and single brace type. And then stress, deformation, mode shapes are analyzed and compared. The results present that stress, deformation and mode parameters of two models make little differences in the same load case. Therefore, adopting single brace type doorframe and thus heightening contact crossbeam is feasible, which could reduce steel cost and enlarge room below the contact crossbeam.
