Arch Space Frame
An arch space frame is a structural system that combines the load-bearing efficiency of an arch with the lightweight, rigid properties of a space frame. This hybrid design is used to create large-span structures that can withstand significant loads while minimizing material usage.
Curved Arch + Space Grid: The structure consists of a three-dimensional truss following a curved (arch) profile.
Interconnected Elements: Made of linear members (struts) connected at nodes, forming triangular or polygonal units.
Materials: Typically steel or aluminum for strength and lightness; sometimes reinforced concrete or composites.
Arches naturally transfer loads as compression forces along their curve.
Space frames distribute loads in three dimensions, enhancing stability.
The combination allows for longer spans with fewer supports compared to traditional arches.
Single-Layer Arch Space Frame: Simpler, used for moderate spans (e.g., canopies, small roofs).
Double-Layer Arch Space Frame: More rigid, used for large-span structures (e.g., stadiums, hangars).
Tied Arch Space Frame: Uses tension cables or ties to counteract outward thrust, reducing foundation loads.
✔ Large Spans Without Intermediate Supports – Ideal for stadiums, airports, and bridges.
✔ Lightweight Yet Strong – High strength-to-weight ratio reduces material costs.
✔ Aesthetic & Functional – Smooth curves allow for visually striking designs.
✔ Modular Construction – Prefabricated components speed up assembly.
✔ Good Resistance to Dynamic Loads – Performs well under wind, snow, and seismic forces.
Stadiums & Arenas (e.g., Olympic stadiums, indoor sports halls)
Airport Terminals & Train Stations (e.g., large-span roofing)
Bridges & Viaducts (arch-space frame hybrid bridges)
Exhibition Halls & Convention Centers
Industrial Sheds & Aircraft Hangars
Bird’s Nest Stadium (Beijing, China) – Combines a steel space frame with an arched lattice shell.
Milwaukee Art Museum (USA) – Features a movable arched space frame roof.
Singapore Sports Hub – Uses arch-supported space frames for its domed roof.
Arch space frames are an advanced structural solution for long-span, lightweight, and aesthetically pleasing designs. They merge the best of arch action and space truss efficiency, making them ideal for modern architecture and engineering.
