Research Report RP20-5
This example provides a step-by-step strength calculation of a 4-span continuous Z-purlin system supporting a standing seam roof.
Design inputs are defined first, including cross-section dimensions and orientation, span lengths, roof slope, and bracing provided by the standing seam to the purlin line. The calculations consider gravity (downward) and suction (uplift) loadings.
