Five support methods of space frame structure

The support methods of the space frame structure include peripheral support, point support, combination of peripheral support and point support, two-sided and three-sided support, etc.

As the roof of a large-span building, the space frame structure should firstly meet the requirements of the building layout and the use function of the building. This structure has greater spatial rigidity and is more sensitive to the rigidity and stability of the supporting member. From a mechanical point of view, the support of the frame structure can be divided into two types: rigid support and elastic support.The former means that there is no vertical displacement under load, there can be horizontal displacement, or no horizontal displacement. It is generally suitable for the space frame to be directly placed on a column, wall, or reinforced concrete beam with greater rigidity;The latter generally refers to the situation where the free side of the three-sided support space frame is equipped with anti-beam support, truss support, and cable support.

When it is not allowed to set up columns on one or both sides of the space frame at the expansion end of industrial plants, hangars, hull workshops, gymnasiums, etc., the space frame needs to be designed in a form that supports three sides and one side is free. Mixed support is suitable for large steel column industrial plants, warehouses, exhibition halls and other buildings.
