Critical Observations In Regards To Primary All-Steel Structural Framing Choices
There are some similarities along with some specific differences for all steel structural framework assemblies. For the entire building to act efficiently it should have lateral structural bracing atop the rafter’s compression flange. Snow, dead, and live loads create pressure upon the topmost flange of the primary building component building framing materials to result in compression. There is sufficient structural bracing supplied by building roof purlins, though. Bottom flanges require steadiness to be applied because this is the portion of the frame subject to compression from the energy of wind uplift. The specific steel building manufacturer’s engineering section determines the exact areas of any flange bracing.
