Commercial Timber Structures (Part 2)

Big Potato Restaurant, South Australia.

Glulam beams for the Big Potato Restaurant, South Australia.

The Big Potato restaurant in South Australia was engineered by Connell Wagner Pty. Ltd. Another photo of the roof structure before the plywood (or LVL) roof was installed can be seen here.

The central pyramid is acrylic, possibly similar to the Okinawa Churaumi aquarium. It's purpose is to let in sunlight. Acrylic does not shatter like glass as it is a plastic product.

Double member trusses.

Double member trusses installed.

For the double member trusses above, a metal splice is inserted at each joint followed by the bolts and large washers.

was wondering if you could share some more details about the double member trusses. If you have any idea on the design of them and or if you know someone who does

Thanks in advance

Tietje_3: We used to use the computer programs L (from UNSW, Australia) and MicroFEAP II (from AIT, Thailand) which could analyse both pin-jointed trusses and frames. However I believe these programs are now very well dated as they ran under MS-DOS. I don't know what software is presently being used for truss analysis. If analysis is done by hand and calculator, the method of sections or method of joints can be used. The stress on each double member bottom chord would be half the stress if only one member exists.
