9mm Assume that the design wind pressure (p) for the Main Wind Force-Resisting portion of this scaffolding and
the Cupola is p = 30psf windward and 25 psf leeward. Assume that all modiﬁcation factors have been
applied to these wind pressures. Assume the following dimensions for the elements labeled in the illustration above (previous page):
U = 8 feet (east/ west width of the Cupola) V = 8 feet (north/ south width of the Cupola) W = 10 feet (height of the Cupola) X = 20 feet (east/ west width of the scaffolding at the lower level) Y = 20 feet (north / south width of the scaffolding at the lower level) Z = 12 feet (height of the lower level scaffolding) In each of the questions pertaining to the scaffolding ignore any scaffolding above the level demarcated by
the letters A, B, and C. Inchdefteebpdydiaggams summarizing the .bads andxeacﬁnns foreadl of the questions. No buffeting or
wind shedding need be considered. Clearly state and label E tribunazry areas in your calculations. ﬁngtign LA, Calculate the full windward wind load acting on area BCEF (demarcated with letters in the above
illustration) from an East/ West wind that generates the full design wind pressure (p). Assume that the
entire area of the scaffolding area BCEF is enclosed with the white fabric scrim so that the entire area

• Please add: Full windward load = Cd x p x A ; Cd = coefficient of drag = 2 for flat wall; Load = 2 x 7200 = 14,400 pounds
