In this paper, the long-span cable-stayed truss structure in port for ore transportation along the coast is taken as the analysis object, with the static three-point force coefficient which obtained based on numerical wind tunnel simulation, the buffeting response of structure induced by turbulent wind load is studied by time-domain analysis method. The results show that the amplitude of buffeting response induced by turbulent wind load is larger than that of static wind load and it is also found that the increase of the main girder retaining wall and the operation load have great influence on the buffeting response of the structure. The research results can provide a strong theoretical basis for the design of the project and similar projects.
