What Is a Space Frame Structure?

A space frame is a simple, truss-like structure made of geometrically interconnecting struts. They are a typical element in contemporary architectural design.

Space frames include several spans, which are frequently utilized to meet longer spans with fewer supports. This is their key advantage over PEB.

This article will go into greater detail about what space frame architecture is as well as the various categories.

Introduction of Space Frame Structure

A rigid, lightweight, truss-like structure is what is referred to as a space frame structure. It is made of geometrically arranged interconnecting struts. Large expanses can be effectively covered with space frames using little internal support.

The inherent stiffness of the triangle and the bending loads—tension and compression loads—transmitted along the length of each strut are what give a space frame construction its strength.

Types of Space Frame Structure

Depending on their curvature and constituent groupings, space frame structures can take many various forms. Ahead, we discuss them.

Classification based on curvature:

  • Space plane covers: They comprise the planar substructures that comprise these Spatial Structures. They exhibit planar deflections and behave like a plate. Shear pressures are directed through horizontal bars and supported by diagonals.
  • Barrel vaults: These are barrel-based vaults with a straightforward arch cross-section. The support for this kind of space frame does not always need to consist of tetrahedral modules or pyramids.
  • Spherical Domes: To make spherical domes and other complex structures, tetrahedral modules or pyramids are frequently employed, along with additional support from a skin.

Classification based on arrangements of its elements

  • Single layer grid: a single layer of components that make up a structure's exterior.
  • Double-layer grid: Flat and double-layer space frames are frequently employed. In double-layer space frame constructions, the elements are placed in two parallel layers that are spaced apart by a predetermined amount.
  • Triple layer grid: The components are set up in three parallel lines joined by diagonals. Almost always, they are flat. practically applied to a construction with a wider span.

Advantages of Space Frame Structure

  • Space frame constructions are highly robust. They enable the most accurate load sharing.
  • These buildings are structurally sound, lightweight, and portable.
  • It has a low deflection and can support heavy weights.
  • Platforms or overhead structures that span large distances can be built using space frame trusses without the need for internal load-bearing support.
  • Compared to a traditional steel structure, it offers minimal shipping expenses.
  • Maximum seismic resistance is also provided by space frame construction.

Disadvantages of Space Frame Structure

  • The height of the space frame structure can only be 40 feet when reinforced concrete is used.
  • In a three-dimensional plate construction, space frames are made up of linear components that only react to axial tension or compression.
  • The effect of bending or torsional moment is minimal, despite the fact that some connections have quite stiff joints.
  • The joints of prefabricated components in space frames frequently leak.
  • Transportation expenses could be more expensive than those for prefabricated volcanic parts.
