Compared to traditional concrete structures, grid structures can significantly reduce the weight of buildings and lower foundation costs.
3. Uniform spatial force distribution
The grid structure transfers loads through three-dimensional members and nodes, with uniform force distribution, and can effectively disperse external loads.
Has excellent seismic and wind resistance performance, suitable for earthquake prone areas or areas with high wind loads.
4. Flexible and diverse shapes
The grid structure can form various geometric shapes according to design requirements, such as planar grid, curved grid, spherical grid, etc.
Capable of meeting the needs of complex architectural forms and enhancing the aesthetics and artistry of buildings.
5. Fast construction speed
The members and nodes of the grid structure are prefabricated in the factory and only need to be assembled on site, resulting in high construction efficiency.
Modular design and installation methods further shorten the construction period.
6. Good economic viability
Low material usage, fast construction speed, and low overall cost.
When applied to large-span buildings, it is more economical compared to traditional structures.
7. Environmental protection and energy conservation
The grid structure adopts recyclable materials, which conforms to the concept of green building.
Natural lighting and ventilation can be achieved through design optimization to reduce building energy consumption.
8. Wide applicability
Suitable for various types of buildings, such as sports venues, exhibition centers, industrial plants, airports, stations, coal sheds, etc.
