NBCC 4.1.5.14 Loads on Guards
(OP)
Hello All,
I'm about to be doing battle with a compliance architect for guard rails. Project specifications note, “railing assemblies and handrail attachments are to resist lateral force of 1kN at any point without damage or permanent set.” The load of 1.0kN is in accordance with NBCC 4.1.5.14 sentence 1 b); however, I interpreted the project specification to mean the guards need full resistance (per CSA-S16) but a load factor in excess of 1.00 could be omitted as the load needs to be resisted without permanent set. The compliance architect is of the opinion that a load factor of 1.50 should have been considered. Honestly, I don't have a strong opinion one way or another and feel this is a grey area.
Who agrees one should include a live load factor for loads on guards, and who agrees load factor could be considered to be 1.00?
Thank you in advance for your replies and comments.

Also, the whole "without damage" to me implies a service load to me. I'd hate to take something to an "ultimate" level and claim it was "without damage".

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
