Description: Structural diaphragms are used widely to stiffen and brace farm buildings, particularly insulated buildings having both exterior and interior claddings. Here, diaphragms are often the most suitable means of resisting the horizontal components of wind force. The critical farm building design problem is usually wind that blows perpendicular to the long walls as in Figure 1. Alternative forms of wind bracing, such as knee bracing from the walls to the roof trusses, are often employed. Knee bracing is particularly unsuitable for buildings where walking passages are located next to the outside walls here the open rectangular box made possible by ceiling and endwall diaphragms is a much better alternative. There are practical limitations to the length/breadth ratio of a ceiling used as a structural diaphragm, but the great majority of insulated farm buildings are proportioned within these limitations. Wind forces for design of most building shapes, including typical gable-roofed farm buildings, can be estimated from the Canadian Structural Design Manual (2). Basic principles for design of fir plywood diaphragms are outlined in a technical bulletina, and Turnbullb further developed these principles as applied to typical Canadian farm buildings.
