The structure is described as a Big Top Tensile type mechanically tensioned membrane structure, of traditional design except for the use of 100 millimetre strips of 900 GSM fabric to reinforce the flat plane of the roof running down the seams.
The Big Top has 2 king poles, with 2 bellrings, on which the membrane of the tent is attached. The plastic membrane is then attached to the bellrings and laced to each other. These bellrings are pulled up mechanically and raise the “points” of the Big Top up the kingpoles. The outside of the Big Top has side poles which stand the roofing membrane 5.0 metres from the ground. Each of the side poles is tensioned with 5.0 tonne ratchet straps.
These big tops are reinforced with so many different webbings and strips of fabric that even if the panels were removed, the structure would still stand! Big Tops have panels stitched on or radio-frequency welded together, which radiate from a central suspension point out to the side points. These emanate from the centre, or sometimes from the King Pole, to the outside poles or Side Poles. Where any pole is placed under or through the plastic structure, all these points are specially reinforced.
