1. The ash load of space frame steel structure is a load that must be considered in the construction and metallurgical industries. This is uniform throughout the country and is about 0.5KN/m2 or LOKN/m2. However, if it is in the power plant or coal industry, the production environment of the space frame steel structure of the coal storage plant inside is relatively good, and it is not necessary to consider the ash load. At the same time, the heavy load in the snow load or roof load should be considered together with the ash load.
2. Snow load is also an important load for space frame steel structures. Snow load is a sensitive load for larger span structures. In many countries, accidents of space frame steel structure collapsing in heavy snow have occurred, in cold areas with snow. It is necessary to consider the snow load, as well as the uniform, uneven and semi-uniform distribution of the roof.
3. three main reasons affect the distribution of snow load on the roof. They are wind factor, roof shape, and roof slope factor. The unevenly distributed snow load in the space frame steel structure generally has a controlling effect. In the regulations, the snow load generally needs to be considered simultaneously with the ash load.
