Re: Canada Snow Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Climatic for Kenora

Ss = 2.1 Kpa (44 psf) with additional Sr = 0.3 Kpa (6.5 psf)

Ss is ground snow  therefore normal roof load for design would be

S=Ss(Cb x Cw x Cs x Ca) + Sr

S = (44)(0.8 x 1 x 1 x 1) + 6.5 = 41.7 psf
