Load combination including the temperature
Load combination including the temperature
(OP)
The effects of temperature in ACI318-11 are left to the engineer judgment where the load combinations does exclude the effect of T.
When dealing with temperature on a roof slab where temperarure is considered due to the external exposure of the slab, what is the load combination including the temperarure that you use? Using 1.2DL + 1.6LL combined with 1 x T is too conservative since it is unlikely to happen. So it would like what do you do in practise.
Thank you

Is the bottom of the roof slab exposed to conditioned space?
RE: Load combination including the temperature
Personally i am thinking to 1.2DL + 1.0 LL + 1.0 T , to combine it in some non linear analysis in order to reduce the effects of restraint and temperature.

Yes for ACI and ASCE 7-10 it is kept to the engineering judgment, however you can still take some guidelines from different codes to have an idea.
