In addition, you can estimate/verify your snow loads Section 100 General Requirements thru Section 200 Basic Definitions, Assumptions, and Limitations of the Prescriptive Code. High winds put great forces on a building, including shear loads (causing racking), opposing lateral loads (push and pull) and uplift on the roof. This worksheet assumes either Enclosed or Partially Enclosed buildings, and does not consider open buildings. Nonmembers will have view-only capability. For an enclosed or partially enclosed building to be classified as a Low-Rise building, the following 2 conditions must both be met: For Transverse Load Case the roof pressure coefficient, GCpf, when negative in Zone 2 or 2E, shall be applied in Zone 2/2E for a distance from the edge of the roof equal to 0.5 times the horizontal dimension of the building parallel to the direction of the MWFRS being designed or 2.5*he at the windward wall, whichever is less; the remainder of Zone 2/2E extending to the ridge line shall use the pressure coefficient GCpf for Zone 3/3E.
