A printed document (referred to in FDB1/18/785b), illustrating the design principles of an 'A' frame structure.

Date unknown

From: 1965 To: 1965

The text reads: "1. The 'A' Frame This is a well established design which is probably the most adaptable building frame available. Where a low cost of square foot per covered space is the prime consideration, the 'A' frame is ideal, ensuring a building of maximum strength and permance, consistent with economy. Ample roof space is provided with the 22 1/2 degree standard roof pitch but, for certain applications, the frame can readily be provided with a 11 3/4 degree half-pitch roof. Based on a centre-line multiple of 15ft., structures of any length can be erected and additional bays or spans can be added at any time with minimum expense and inconvenience. Lean-to additions having an 11 3/4 degree or 22 1/2 degree pitch and upward or downward canopies are also available and 'K' frame components can be incorporated to provide a first floor." An annotation of the 'A' frame diagram reads: "Portal Structure Spans: 15ft to 70ft in 5ft standard increments. Eaves height: up to 22ft in 1 ft increments. Bay lengths: 15ft standard multiples (up to 20ft optional). Roof pitch: 22 1/2 degree or 11 3/4 degree."
