A space frame is a truss-like, trivial stuff structure built from interlocking struts in a geometric pattern. They are a common feature in modern building construction. The main advantage of Space Frames over PEB is that it uses a multi-span, and is often used to meet a longer span with few supports.

They are strong due to the characteristic rigidity of the triangular frame; Flexing loads (bending moments) are transmitted along the length of each strut in the form of tension and compression loads. Space Frames are built from correlated members and nodes. The members and nodes are connected by bolts.

The size of the members, nodes, and high tensile bolts are determined by the structural design. Space frame building is a new alternative to pre-engineered building systems. SFBS are extremely rigid and stable compared to any other existing structural systems. It is widely used in all international air terminals.

Appropriate research and development were done to make this system applicable for industrial/institutional applications. Its spectacular beauty and robust appearance make it a good choice for architects and structural engineers to use SFBS in their projects.

The important part of architecture is the designing process in which a blueprint of the structure is made, as it lays the foundation of great structures. Creating an architectural structure requires highly creative and innovative skills to produce the final design. Steel structure requires the right analysis, materials, construction technologies, and building systems to truly scale new heights.


Steel structures are concerned with the design, description, construction, maintenance, and application of science to improve steel materials. It helps to come out with a range of extraordinary architectural structures.

Components of Space Frame System

Axial members known as tubes form the key components of this type of structure.

These tubes can have circular hollow sections or rectangular hollow sections which can be connected to each other using connectors.

There are four main types of connectors, namely tubal node connectors, nodus connectors, triode tic connectors, and hemispherical dome connectors.

The type of connecter used in this type of structure depends on the type of tubes as well as the total design and robustness requirements of the structure.

All of the above features combine to make space frame structures extremely lightweight, elegant, and economical. They offer greater flexibility in terms of integrating various lifestyle features within the structure in a highly intuitive, smart, and hassle-free manner.

Advantages of Space Frame Structure

Space Frame Structure has following advantages,

Space frame structures are easy for transportation, handle, and stack.

It offers adjustable cambering features.

Very easy to install on-site due to fast installation or prefabricated components.

It does not require purlins.

It is more suitable for structures that have irregular plan shapes and sites.

Also, suitable for a structure that has a large span.

It provides a column-free explicit word.

It provides a big spawn at low altitudes.

It provides minimum deflection.

The space frame structure also has maximum seismicity.

It has an excellent span-to-depth ratio.

It provides low transportation costs.

It is lightweight and structurally effective.

Concentrated loads are distributed evenly throughout the structure.

It has very good acoustic properties.

Disadvantages of Space Frame Structure

Some Disadvantages of Space Frame Structure are as follows,

When reinforced concrete has used the construction of a space frame structure is limited to 40 feet.

Space frames that span a three-dimensional plate structure are based on the rigidity of the triangle and are composed of linear elements that are usually only subjected to axial tension or compression.

Even though there are some connections that are comparatively rigid joints due to bending or torsion effects that is insignificant.
