Seismic Loading: D1 seismic design category per I.R.C.
Sns= .83, R =6.5, W=weight of structure
V= [1.2 Sps/(R x 1.4)]W
V= .109W
Roof Dead load= 15 psf
Exterior Wall Dead load = 12 psf
Interior Wall Dead load=8 psf
Floor Dead load= 12 psf
Seismic in front to back:
Wr=[.109(40')(15+6+4)] = 109plf < 148.9plf therefore, wind governs.
W2 = [.109 (40')(12+12+8)] + [.109(20')(15+6+4)] + 109= 303p1f < 317.2plf therefore, wind governs.
W1 =[.109 (35')(12+12+8)] + 303 = 425.1 plf < 467.8plf therefore, wind governs.
Seismic in side to side:
Wr=[.109(40')(15+6+4)] = 109plf < 149.8pIf therefore, wind governs.
W2=[.109 (40')(12+12+8)]+ 109= 248.5pIf < 323.5plf therefore, wind governs.
W1 =[.109 (40')(12+12+8)] +248.5 = 388.0ptf < 462.3plf therefore, wind governs.
Redundancy Factor= 1.0 per ASCE?section 12.3.4.2
