How to calculate the load of space frame steel structure?

The main loads of space frame steel structure are divided into three kinds, which are action load, permanent load and variable load. Generally speaking, the loads include the self-weight of space shell structure, the self-weight of roof maintenance structure, the load of suspended equipment pipe and the load of horse path. For the storage silo, there are four kinds of variable loads, which are roof load, snow load, wind load and ash load, so how to calculate the load of space frame steel structure?

Firstly, the ash accumulation load of space frame steel structure is a kind of load that must be considered in construction and metallurgy industry, which is unified in the whole country, 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 better, so it can not be necessary to consider the ash accumulation load. At the same time, snow load or roof load in the large load, should be considered together with the accumulation of dust load.

Secondly, snow load is also an important load of space frame steel structure, snow load is a sensitive load for larger span structure, in many countries there have been accidents of space frame steel structure collapsing in snowy days, snow load must be considered in cold areas with snow, and should also be considered in the case of uniform, uneven and semi-uniform distribution of the roof.

Thirdly, there are three main reasons affecting the distribution of snow load on the roof, which are wind factor, roof shape and roof slope factor. Unevenly distributed snow load in the space frame steel structure will generally have a controlling effect, and snow load generally needs to be considered at the same time with the accumulation of dust load in the regulations.
