Looking for Snow Load and Wind Load 3

[Mustafinho]

I am looking to find the Snow Load in the Ontario Building Code (OBC) and looking at (Part 4 - Structural Design) 4.1.6.2. where the specified snow load formula is provided, I can't find the Ss, which is 1-in-50-year ground snow load (kPa) determined in accordance with subsection 1.1.2.

Subsection 1.1.2. in the OBC is the Climate Data. It requires Supplementary Standard SB-1 values from climate and seismic design values.

Similarly, the specified wind load also has a q value, which is determined in conformance with Subsection 1.1.2.

Normally, I use Jabacus to get both Snow and Wind Load values but I want to be able to use the OBC to do it manually.

I am guessing I might have to use the NBCC to get the values(I have never used NBCC at school/work) since most of the work was for Ontario.

Where can I find the climate and Seismic design values?

Thank you in advance for your input.

Just buy the complete Ontario Building Code !

Appendix C of the NBCC. I would expect that the OBC uses the same values.

I had bought the complete OBC 2006 but I don't see the climate data anywhere!

 

[Mustafinho]

I understand that the NBCC will have it but it doesn't make sense for the OBC to not have the "Climatic and Seismic Information for Building Design in Ontario" which is under Supplementary Standard SB-1.

It should be included in the OBC. Can some one provide me the section and/or division in the OBC where that is listed?

IF the OBC is telling you to get SB-1 then it's likely in SB-1. No other way around it.

Why aren't you using the 2012 version?

Here locally (Texas)- if a city adopts a particular building code, then the local public library will invariably have a copy of that code in their reference section. Have no clue if that works in Ontario, but if you're physically located there and don't often need the standard, it's worth a shot.

It is in the SB-1. Where is the Project?

Also- look at

http://www.jabacus.com

that will help.

And yes- you need the 2012 edition. Snow loads increased by about 10% almost across the board, although I believe that was in the 2006 edition.

Also, did your complete package come with the National Building Code user guide/commentary book? Irritatingly, most of the diagrams you need to do wind loading are in the commentary.
