Space frame
Short members form a lightweight three-dimensional grid for broad prefabricated roofs.
Repeated nodes and struts can be factory-made and bolted together on site, making the system common in arenas, exhibition halls, and airports.
Loads travel mainly as axial forces through flat, curved, or domed grids. Module size controls both appearance and fabrication cost.
Pompidou and high-tech roofs expose a machine-like lattice, sometimes using its depth to accommodate services.
Corrosion, node quality, and steel behavior in fire shape maintenance. Protective systems and recoating cycles should be specified.
