Roof snow load calculation(per ASCE 7-16)Design roof snow load =29 psf
Ground Snow, pg =47 psfRoof pitch 6 :12
Flat roof snow load, pf = 0.7 Ce Ct Is pg (Eq. 7.3-1)
Ce =0.9 (Table 7.3-.1)Ct =1.2 (Table 7-3.2; cold roof with solar panels)Is =1.0pf =35.5 psf
Sloped roof snow load, ps = Cs pf (Eq. 7.4-1)
Cs =0.8 (From Figure 7.4-1b, slippery surface)
ps =28.4 psf(1 psf reduction from design roof snow load)
Roof Trusses (designed according to R802.10.1)
35 # Snow and 90 mph winds (Local Conditions)
