Abstract: Aiming at the external influence of outdoor cranes to the wind loading, first of all, the wind loading was classified and the main beam was simplified to a reasonable model. Main beam stiffness and strength were studied at an average wind loads. Based on the static force, the size of the model wind load was calculated under the eight level winds, and the crane girder was calculated by the finite element software in the wind loads and no wind loads. Compared with them, the results indicate that there will be tiny influence on the vertical static deflection and maximum stress of the crane. However, it has impact on the horizontal displacement. In the study of crane, it provides the reference value about closer to the actual establishment, and the reference model to the further optimization and lightweight design of the beam.
Key words: crane girder; wind loads; finite element
