Ripley, Ontario Canada | 60 feet is rather common here too. Some dairy barns are wider yet, 80 feet, although some are split trusses with posts in the middle. Check that your snow load is right, make sure it is a non windswept snow load (they won't build anything else here after a few barns went down from snow load). If you are worried up the snow load to 50 pounds and make sure you get a brace drawing from the truss builder. Make sure all the braces go in the right place, call them if you are not sure, the braces are what make the truss roof strong. | |
