Space
frame:
A
space frame
is
defined
as
a
spatial structure whose members are connected
rigidly with
each other
to
allow large column free spaces which has always been a requirement
for conventional building. The roofing of steel space structure
is supported on steel columns to provide a covered space with
uninterrupted viewing of the central arena. Applications
of space frames include architectural, aerospace, automotive
structures and many more such
as
Community
Halls, Industrial Buildings, Bridges, Convention
Centre,
Exhibition
Halls,
Railway platforms, Sports stadiums, Barrel vault Structure, Dome
structures etc.
Convention centres
are intended for use by domestic as well as international business
travelers. Aim of constructing Convention Centres and Exhibition Halls
is to meet the requirement of lucrative segment for the tourism
sector. In manufacturing these structures by space frame technology,
various suitable techniques are presented and
investigated for design optimization of lightweight space-frame
structures considering structural mechanics.
In
Convention Centre and
Exhibition Hall,
the roof structure comprised of an external fully exposed space frame
(known as exoskeleton) and secondary roof structures suspended from
the exoskeleton. The roof structure
may also comprises pairs of curved welded trusses, with space frame
spanning between them, along the longitudinal and latitudinal axes.
In case of any customized requirement, these structures can be fully
welded structures using special purpose designed nodal assemblies.
