2. DEFINITION:
A three-dimensional structures.
The assembled linear elements are arranged to
transfer the load.
Take a form of a flat surface or curve surface.
Designed with no intermediate columns to create
large open area.
4. TYPES OF SPACE FRAME
1) Two and three-way grids
Characterized as two way or three way
2) Single, Double and Triple Layered
Single layer frame has to be singly or doubly
curved.
Commonly used space frames are double
layered and flat.
Triple layered is practically used for a large
span building.
7. CONNECTORS
1) Tuball Node Connector
A hollow sphere made of spheroidal graphite
The end of the circular hollow section member
to be connected is fitted at its ends by welding.
Connection from inside the cup is using bolt
and nut.

9. 2) Nodus Connector
It can accept both rectangular and circular
hollow sections and that the cladding can be
fixed directly to the chords.
Chord connectors have to be welded to the
ends of the hollow members on site.

11. 3) Triodetic Connector
It consists of a hub, usually an aluminium
extrusion, that has slots or key ways, which the
ends of members are pressed or coined to
match the slots.
12. 4) Hemispherical Dome Connector
Usually use for double layer domes.
Has a span more than 40m.
More economical for long span.
The jointing is connect by sliting the end of the
tube or rod with the joint fin.
There are 2 types of joint, pentagonal joint and
hexagonal joint.

14. ADVANTAGES
Light
Elegant & Economical
Carry load by three dimensional action
High Inherent Stiffness
Easy to construct
Save Construction Time & Cost
Services (such as lighting and air conditioning)
can be integrated with space frames
Offer the architect unrestricted freedom in
locating supports and planning the subdivision
of the covered space.
