load combination used when checking the deflection of purlins.
(OP)
can anyone clarify the load combinations that should be used when checking the deflection of purlins ?
Should the wind load be included in the vertical deflection of the purlins???

Is it ok to check the wind load separately without combinig it with other loads ?

Most other codes have the same requirement.
Wind doesn't know whether the roof is already loaded with live or snow loads.

However, I think you will find that most engineers only consider wind uplift even though technically wind can produce a downward force on the roof as well.
