Abstract：Due to lack of reference,values determination of the structural shape factor of wind load and the wind pulse-vibration factor has become a problem for the design of closed belt conveyor corridor.So,we took the coal and ore conveying project of a wharf in Indonesia as an example,compared with the relevant provisions of Chinese,American and European codes,and carried out 3D model calculation and analysis using MIDAS finite element software.The results show that:The values of structural shape factors of conveyor corridor or semblable structures are close in different countries'codes.The wind load structural shape factor is affected by wind direction angle,and there may be a wind pressure concentration area at the end of conveyor corridor,which should be considered in the force and deformation calculation.The designers should pay special attention to the stress of corridor support under the action of uneven wind load.
