Experimental investigation of wind load on large-span dry-coal-shed latticed shell

Wind tunnel experiment was carried out based on the dry-coal-sheds of the power plant according to the engineering design and experimental study's need.The impact of wind direction and coal piles on structural shape coefficient were taken into account as well as the elevation-angle of the dry coal shed.By data analysis,extremum of shape coefficient were obtained.The surface of the dry-coal-shed was divided into seven areas and seventy-seven areas according to the shape of the dry-coal-shed and different load cases.Shape coefficient of the dry-coal-shed was given and compared with the values of standardized.Some conclusion were obtained.The experiment may supply the design reference for dry coal shed expanding or similar project.
