National Building Code of Canada VS. IBC

National Building Code of Canada VS. IBC

National Building Code of Canada VS. IBC

(OP)

How does the National Building Code of Canada seismic design compare to the IBC? Is the methodology similar?

RE: National Building Code of Canada VS. IBC

Probably - get a copy of both codes and do your homework...

RE: National Building Code of Canada VS. IBC

(OP)

I might have a tiny job in Canada, with a local registrant who will seal it. I'm not going to buy the code on the off chance that I get a very small job.

All I am trying to find out right now is: If I get the job, will I be learning a new seismic design method, or will it be similar to the IBC.

RE: National Building Code of Canada VS. IBC


Similar to ASCE 7-05

RE: National Building Code of Canada VS. IBC

hawkaz;
Having worked with both codes, I can say the the design philosophy in NBCC is based on research done for IBC in southern california. The equations and base shear calculations are different, but the research behind it is the same.

Depending what area you are designing for seismic may not govern.

Hope this helps.

RE: National Building Code of Canada VS. IBC

Where is your job? Seismic concerns are next to insignificant in an awful lot of the country.

RE: National Building Code of Canada VS. IBC

You'll still need to know the methods enough to prove that, though. Even some very low seismic areas can have some small forces that need to be calculated if you have unfortunate site conditions. Unless you're more comfortable with the code and areas of the country you'll still have to do the math that shows it's a lower force than whatever other lateral forces may govern.

RE: National Building Code of Canada VS. IBC

Which area of Canada? Manitoba uses the NBCC, but sets Sa(.2)=0.0 which effectively negates seismic design.

RE: National Building Code of Canada VS. IBC

Yea, True for manitoba...

But not for western and eastern canada you can go up to 2.3 g design acceleration (La Malbaie, Quebec) ! It's about 0.69g at montreal (high frequency content ~ higer mode excitation), and 0.94g for vancouver (low frequency content)

Depending of the height of teh building seismic generally control over wind in these areas !

So it really depend on where your project is located .

This is Toronto. I don't expect seismic to even be close to governing- but as TLHS indicated, I will need to prove that and provide the seismic info in my General Structural Notes.

Thanks

RE: National Building Code of Canada VS. IBC

When I left Toronto, Ontario had its own Building Code and last I knew the 2006 Ontario Building Code was in effect... best you try to obtain the code in effect. The OBC was a re-write of the preceeding NBCC... and may be the 2005 edition of the NBCC.

They had a separate document. In Manitoba, we reference the NBCC, but with modifications.

About 20 years ago, there was a minor tremor in Toronto... felt like a heavy vehicle passing if you are on the second floor... this was slightly felt on the 8th.

RE: National Building Code of Canada VS. IBC

Should have added that we use Imperial and Metric... about 90% of the work I do uses Imperial Units, exclusively. From my experience, only the Government and the people in Alberta use Metric. Others may have different experiences.

Dik

RE: National Building Code of Canada VS. IBC

Really? All the industrial I've done recently have been metric except for one. That one only uses imperial because they want to be able to easily maintain their 40+ year old process and piping drawings.

RE: National Building Code of Canada VS. IBC

Was just a headzup to check the Code and Units for the work...

RE: National Building Code of Canada VS. IBC

Ontario Building Code

Link to the Ontario Building Code you can read it online.

sounds like you would be looking for Part 4 Structural Design.
