Re: [EXTERNAL] Re: Type V Construction & Hangers

Wow, it almost seems like a waste of time to even employ a structural engineer to design the roof structure, only to have another structural engineer prove every individual load. Mark at Aero 602 820-7894 Sent from my iPhone On Sep 25, 2018, at 4:46 PM, John Denhardt

In one jurisdiction, it has been that way for over 20 years to require a structural certification any time we are installing any pipe over 2” in any type of construction. Yes I do say any type of construction! John John August Denhardt, P.E. Strickland Fire Protection On Sep 25, 2018, at

RE: [EXTERNAL] Re: Type V Construction & Hangers

I look back over the past million or more hangers we’ve installed and can’t think of a single time anyone has called to say one failed. Mostly when we have heavy loads, say 8” heavy wall, we tighten up the spacing, maybe 8’ oc, or even just install trapeze bars to spread out the point load. We

RE: Type V Construction & Hangers

Maybe so, but here's the thing: if you apply the seismic load factors (as you're supposed to in the building code) to standard details from companies like TJI, you'll be shocked to find that their "pre-engineered/pre-approved" details aren't adequate. I've been shown where the value of a 10d

Type V Construction & Hangers

Has anyone run into situations where the AHJ is requiring the structural engineer on a project to provide a sealed criteria letter for the project indicating the maximum hanger spacing based on pipe size and structural member? We are seeing one local jurisdiction start to require this.

PRYING FACTORS

So, this is the first time I've needed to apply the 2016 ed. prying factors for seismic. I'm confused to say the least. I'm looking at one particular manufactures wedge type anchor. It has a Pr factor and then a corresponding weight load. For example, 3/8" anchor, Figure A, has a Pr of 2.626 @
