Spatial structure refers to a structure made of an assemblage of linear members interconnected to each other in space, resisting loads applied at their connections or along their lenghts.
The design of spatial structures is a collaborative effort between architect and engineer, which typically begins at early stages of the conceptual design. The geometry types, module sizes, support conditions, materials, and design approach are not determinated at the early stages of the design of spatial structures. The members of spatial structures are interconnected, they can distribute loads effectively. This means tat a concentrated load applied at a point on the structure can be resisted by members a large distance from it.
- Due to the low self-weight of these structures, the total costs of foundations and
columns are relatively small. The system is light and more efficient as
materials are used more optimally than in other conventional systems.
- Spatial structures can be assembled in a shop and transported to the site
erection. They require less material then other conventional linear systems
and, therefore, if prefabricated can be an economical long span structural
system. The assembly and erection are easy and fast, requiring unskilled labor.
- The manufacturing of the connections (or nodes) is one of the most important
factors in cost-effectiveness of spatial structures. An ideal connector can be
easily mass produced, used to join members at various angles, and resist the
forces acting on it.
- Due to the low self-weight of these structures, the total costs of foundations
and columns are relatively small.
- Spatial structures can be assembled in a factory and transported to the site
erection. They can be easily assembled and erected using a number of modular
- Using spatial structures for large span systems can provide 15 – 30 % reduction
in the amount of the wieght as compared to other long span structural systems.
- They are highly redundant and statically indeterminate systems. As a result, a
failure of a member does not result in the complete collapse of the structure.
- They are a significant advantage in terms of the fire resistance as compared to
conventional planar structures.
They are very durable when subjected to fire.
- They are easily expandable and demountable with the flexibility of placing
supports at various locations.
Supports can be removed or relocated without endangering the overall structural stability.
- Various regular configurations are architecturally appealing and for this
reason almost all spatial structures are architecturally exposed.
- Flexibility in support locations. Spatial structures can be supported at any
This is advantageous for interior architectural planning.
