Pole Barn Roof Truss Spacing

Especially when steel roof truss spacing is concerned some engineers would argue that it is possible to only have a roof truss spacing of four feet off center even eight feet has been suggested.

Many post frame or pole barn construction use 8 foot spacing between trusses. Truss bracing temporary truss bracing is critical to ensure safety and to protect the integrity of the truss structure until permanent bracing is in place. Pole barn construction spaces the trusses 8 feet apart or even up to 12 feet apart depending on the building design. To support the intermediate trusses that do not align with the 8 o c.

Columns a continuous header is typically installed along the sidewall. Post frame buildings that incorporate 4 o c. The practicality cost effectiveness and ease of construction of pole buildings is based upon efficient use of the fewest amount of materials to do the most work within safe engineering design. Of course local building codes and regulations may also determine how many trusses and the spacing necessary for each post frame structure.

For many traditional stick frame builders trusses spaced 8 feet apart seems unnatural but thanks to the ingenuity of modern engineering it is a very common building design. Large span trusses require multiple pickup points using a spreader bar on the crane. With traditional stick frame construction the trusses are usually spaced 2 feet apart. Hundreds of thousands of pole barns are in use today with trusses spaced every 12 feet or even more.

Pole barn truss spacing. For example you might use a 35 spreader bar on a 70 span truss. Truss systems typically keep the columns spacing set at 8 on center. Post frame roofs in severe weather conditions.
