The characteristics of space frame structure
The space frame structure is a spatial structure composed of multiple poles connected by nodes in a certain grid form. Generally, it is a high-order statically indeterminate structure, which can bear concentrated load, dynamic and asymmetric load well, and has good seismic performance. Widely used in stadiums, theaters, exhibition hall, waiting hall, stadium stands awning, aircraft hangar and other occasions. The structure of the grid has the following characteristics: Advantages 1. Large span - Span can be more than 100 meters; 2. Standardization - All components can be mass produced in the factory, easy to ensure the quality; 3. Due to the interaction between the structural members of the space grid, it has good integrity, large space stiffness and very stable structure; 4. Light dead weight - The structure of the grid depends on the axial force of the bar to transfer the load; the material strength is fully utilized, which not only saves the steel, but also reduces the dead weight
