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

9. 2) Nodus Connector
ï It can accept both rectangular and circular
hollow sections and that the cladding can be
fixed directly to the chords.
ï Chord connectors have to be welded to the
ends of the hollow members on site.
10.
11. 3) Triodetic Connector
ï 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
ï Usually use for double layer domes.
ï Has a span more than 40m.
ï More economical for long span.
ï The jointing is connect by sliting the end of the
tube or rod with the joint fin.
ï There are 2 types of joint, pentagonal joint and
hexagonal joint.

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