The following calculations are for lateral wind and seismic engineering and gravity loading of the beams and columns. The design is based on information provided by
the client who is solely responsible for its accuracy. The engineering represents the finished product. Discrepancies from information provided by the client invalidate
this design. Hom Consulting Engineers shall have no liability(expressed,or implied),with respect to the means and methods of construction workmanship or the

Seismic Loading: D1 seismic design category per I.R.C.
SPS= .83, R = 6.5, W=weight of structure
V = [1.2 SDs/(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 (46')(15+6+4)] = 125.4plf > 113.5plf therefore, seismic governs.
W2 = [.109 (46')(12+12+8)] + 125.4 = 285.8plf > 245.9plf therefore, seismic governs.
W1 = [.109 (23')(12+12+8)] + 285.8 = 366p > 364.4plf th- -fore, seismic governs.
Seismic in side to side:
Wr= [.109 (34')(15+6+4)] = 92.7plf < 128.7plf therefore, wind governs.
W2 = (.109 (34')(12+12+8)] + 92.7 = 211.2pIf < 293.8plf therefore, wind governs.
W1 = [.109 (34')(12+12+8)] + 211.2 = 329.8plf < 416.4plf the,efore, wind governs.
Redundancy Factor= 1.0 per ASCE7 section .3.4.2
