Load Calculation 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 the space shell structure, the self-weight of the roof maintenance structure, the load of the suspended equipment pipe and the load of the cat walk. For 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?

The ash accumulation load of space frame steel structure is a kind of load that must be considered in the construction and metallurgy industry, which is uniform all over our country, about 0.5KN/m2 or 1.0KN/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, the snow load or the large load in the roof load should be considered together with the ash accumulation load.　　

In addition, snow load is also an important load of space frame steel structure, snow load is sensitive load for larger span structure, in many countries have occurred space frame steel structure collapse accident in snowy days, in the cold area with snow is necessary to consider snow load, should also be considered in the roof uniform distribution, uneven distribution and semi-uniform distribution of the situation.　　

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 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.
