SUSPENSION CABLE ROOF LONG SPAN STRUCTURE - Coggle Diagram
SUSPENSION CABLE ROOF
LONG SPAN STRUCTURE
Uses cables to directly carry the roof load
The cross section of the suspension cable has to
greater than or equal
to the restressed cable
To make sure the steel areas of ties/struts have negligible effect on both deflections and forces
More resistant to earthquakes
More sensitive to wind that conventional structures
It must designed not only for
static loads
but also for
dynamic loads
The use of the steel cables, the inner and the outer compression ring that support the load will
help to stabilize the roof
Functional advantages for arenas
The shape is better suited to an array of banked seats
Required
smaller volume of air
than a dome

Stretchable over a ring
The
centre line
is usually a
space curve or circle
It is
capable taking up the tensile forces
which ae
transmitted
to it by the roof membrane
Attempted to shape the ring in such a way it has
a little bending
as possible
The most economical method
It can
cover wide area in part
without using any intermediate column or pillar
Only use
load bearing steel cable
as structure
1 more item...
Lightweight structure
The use of trusses and beams
may be avoided can help in decreasing the weight
of the structure
