Planar Space Frame

Main Features:
Efficient and Rational Load Distribution:

This is its greatest advantage. Loads are transferred to the supports through a geometrically stable system composed of upper and lower chords and web members, in the form of axial forces (tension or compression). Material strength is fully utilized, resulting in significantly superior structural performance compared to ordinary planar trusses.

High Stiffness and Lightweight:

Due to its three-dimensional spatial structure, it has excellent overall stability and very high stiffness. For the same span, it is much lighter than traditional reinforced concrete structures, allowing for larger spans and fewer columns.

Low Structural Height, Efficient Space Utilization:

The height (thickness) of the space frame structure is relatively small compared to its span, saving building space and reducing floor height. The ceiling formed by the space frame itself also has a rhythmic aesthetic.

Convenient Installation and Strong Adaptability:

The members and nodes can be standardized and manufactured in factories, ensuring quality and enabling fast on-site installation (using methods such as overall lifting, sliding, and high-altitude assembly). It can adapt to various plan shapes, such as rectangular, circular, and fan-shaped.

Excellent Seismic Performance:

It is a highly statically indeterminate structure with high redundancy. Even if some members are damaged, the internal forces will redistribute, preventing overall collapse, resulting in superior seismic performance.

Advantages:

Suitable for large spans (commonly 30m-100m or more).

Saves on steel consumption and is cost-effective.

Requires less structural height, saving space.

High degree of industrialization, resulting in fast construction.

Aesthetically pleasing and well-proportioned design.
