Generally speaking, the main function of dry coal shed frame structure is to cover coal fields to prevent coal from being exposed to rain and wind pollution of the environment, is an energy-saving and environmental protection project. The building function of the dry coal shed is mainly a large storage warehouse. So it must have a certain storage and working space, that is, the structure must be able to meet a certain amount of clearance requirements, and its effective use of space cross-sectional shape is trapezoidal, work space envelope near arc. The length and width of the dry coal shed structure are determined according to the need sized capacity, while the height of the structure is determined by the operational requirements of the coal pile and the turbine. Therefore, the structure of dry coal shed shack is characterized by a large span, high height and a wide coverage area.
The development of dry coal shed structure has been 20 years of history, and the main forms of structure used are flat steel frames, plane trusses, flat arches and cylinder space shell structures. According to the comparison of the technical and economic indicators of the dry coal shed structure that has been built, the column space shell has obvious advantages and has become the main structural form of the dry coal shed structure.
