TENSIONED FABRIC STRUCTURES THE COLUMBUS CENTER Inner Harbor Baltimore, Maryland CLOSED TENSIONED FABRIC STRUCTURE
Tensioned Fabric Structure: A structure where the exterior shell is a fabric material spread over a framework. The fabric is maintained in tension in all directions to provide stability. DENVER INTERNATIONAL AIRPORT
PIER SIX PAVILION Baltimore, Maryland OPEN STRUCTURE
CHICAGO’S NAVY PIER
Lightweight and flexible
High strength weight ratio
Little to no rigidity
Loss of tension is dangerous for stability
Thermal values limit use
FABRIC STRUCTURES CANNOT TAKE HEAVY WEATHER CONDITIONS FALSE
FABRIC IS ELASTIC AND STRETCHES Fabric has a strong tensile strength and
will creep (stretch very slightly) only a few percent over 20 years of use.
TYPES OF FABRIC STRUCTURES
Four or more point system when the fabric is stretched between a set of alternating high and low points
Tent - like structures containing one or more peaks supported by poles (masts) or a compression ring that connects the fabric to the central support.
Curved compression members are used as the main supporting elements and cross arches are used for lateral stability.
ALUMINUM FRAME SUPPORT
Combination of several support types.
Connection to concrete foundation pillar
BALE RING / MEMBRANE PLATE
Provide a link between the membrane and structural elements..
Bale rings are used at the top of conical shapes.
Membrane plates accept centenary cables and pin connection hardware.
MEMBRANE Forms the enclosure of the structure. Connections can be glued or heat welded.
