Three pinned hinged frames

Three pinned hinged frames are a very efficient form of
structural design as a result of effective load transmission to
ground. Given this efficiency the glulam material consumption
can be kept to a minimum. Further, three pinned hinged
frames are a very cost-effective solution because the building
foundations can be realised at optimal cost.
All in all, the use of three pinned hinged frames is only
restricted by transport limitations and the challenge to realise
a lightly loaded supporting structure.

Three pinned hinged frames are commonly used to free-span
equestrian halls, recreational buildings, sports halls, industrial
halls and agricultural buildings.
