Abstract: Due to lack of reference, parameter value of wind load shape coefficient and gust response coefficient becomes a design problem for closed belt machine conveyor bridge. Taking the coal and ore conveying project of the wharf in Indonesia as an example, compared with the relevant provisions of Chinese, American and European codes, 3D model analysis was carried out by using MIDAS finite element software. The results show that shape coefficients of conveyor bridge or semblable structure are similar in different countries’ codes. Wind load shape coefficient is affected by wind direction angle. There may be a wind pressure concentration area at the end of conveyor bridge. The force and deformation of conveyor bridge need to be considered by this influence factor. The stress of trestle support under the action of uneven wind load needs to be paid attention to.
