How to Calculate Variable Loads for Space Frame Structures

Space frame structures are widely used in intelligent engineering buildings. After the acceptance of the steel structure space frame project reaches the standard, it will be submitted to the tenderer for application. In order to maintain the excellent characteristics and safety of the space frame structure project and ensure a long service life, the tenderee should pay attention to the maintenance standards of the space frame structure. There are four types of variable loads for space frame structures, namely roof loads, snow loads, wind loads and dust loads. Next, follow the SAFS steel structure space frame company to learn how to calculate the variable load of the space frame structure.

  1. The dust load of space frame steel structure is a load that must be considered in the engineering and construction industry. This is a national unified specification, which is about 0.5kn/m2 or 10kn/m2. However, if it is in a power plant or a coal enterprise, the working environment of the space frame steel structure of the coal storage yard is relatively good, so it is not necessary to consider the load of ash accumulation. In addition, snow loads or roof loads which are very large should be taken into account together with dust loads.

  2. Snow load is also the key load of space frame steel structure. Snow load is a sensitive load for long-span structures. Including many countries, the steel frame structure of the power grid also collapses in snowy weather. In cold areas with a lot of rain and snow, the problem of snow load must be considered, as well as the distribution of uniform, uneven and semi-uniform roofs.

  3. The key factors that endanger the distribution of snow load on the roof are the following three elements, namely wind load, roof shape and roof inclination. The snow load is unevenly distributed in the space frame structure. In the basic manufacturing and planning, the snow load and the gray load must generally be considered together.
