You will open a document that begins with a general description of the post-frame building example, followed by detailed descriptions and calculations of

• design loads
• roof diaphragm panel in-plane shear strength and stiffness
• shear wall panel in-plane shear strength and stiffness
• the portion of the lateral wind load carried to ground by the post frame, and
• the portion carried to ground by the roof diaphragm and shear walls using an on-line computer program, the Diaphragm and Frame Interaction (DAFI) Calculator

Throughout the document you will find hyperlinks to more information about, for example, load, stiffness, strength, and force calculations. For easy navigation throughout the document you may open the Bookmarks tab on the left-hand side of your screen in Adobe.

The key structural connections required to ensure continuous load paths to ground are identified and detailed procedures and calculations for designing each of the key connections are provided. Finally, the documents detail the lateral and longitudinal bracing requirements for the building system.
