Adding Purlin Braces For Pre-Engineered and Pre-Fabricated Steel Buildings
Saturday, November 24th, 2007In the engineering of all-steel buildings effectual purlin bracing requires substantial linkage for any eave and ridge ends. Not guaranteed to stop buckling and failure of the scheme is sag angle or strapping in basic aligned rows, a conventional assembly technique.
Appropriately joined to a solid ridge angle or the channel at the ridge is a row of purlin bracing. With a dual-sloped roof this is to assist with opposition to the pressure created by the assembled force of bracing. One sag angle along the ridge is not satisfactory.
