roof beam deflection calculation
roof beam deflection calculation
(OP)
Hello everyone,
I have a question about the deflection calculation of the roof beam:
When we calculate the roof beam's deflection, should we use the snow load plus live load or snow load plus 0.5 live load?
(assume the snow load is bigger than the live load)
Thank you very much!
Best regards,
Ping

RE: roof beam deflection calculation
As for what snow load to apply, your code/standard should tell you this, but I would be shocked if it were anything other than:
G + Snow (at 25? 50? year return period)
The snow load will be less than ULS, which will be something like a 100 or longer return period value.
Hope that helps,

Bear in mind that snow is a live load.

Typically quite low; 0.25kPa range... More an access load for maintenance than a proper pedestrian live load.

Do Mortuarys have live loads?
