Load Combinations for Ultimate Limit State

[MihaiTB]

Hi!

I would like to include thermal(transient) loads due to pipe in my model. What would my load combinations look like?

Is this correct:

1.25DL + 1.4WL +1.25T + 0.5SL, where DL,WL, and T are Principal Loads and the SL is the companion load

Thanks!

Which building code are you using for design?

 

[MihaiTB]

my apologies, I'm using the National Building Code of Canada (2010), there are some references to transient loads in Commentary A (pg A-6) that came with the code, however I don't really understand what it is trying to say.

Looks like the NBCC,

I would be ok with 1.25D + 1.25T + 0.4W + 0.5S. That would be assuming your T is actually a short term type load not a permanent load and therefore W and S would be companion loading.

Thank you!
