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 @ 173 lbs and Figure
B, has a Pr of 1.002 @ 338 lbs.
If I'm thinking this out correctly, I than need to go to the tables in
chapter 9 and locate the closest match.
Again, for example: Table 9.3.5.12.2(c) Maximum Load for Wedge Anchors in
3000 psi (207 bar) Normal Weight Cracked Concrete
Pr 2.1-3.5 @ 116 lbs, use
116 instead of manufactures 173 lbs
Pr ? 1.1 @ 240 lbs, use 240
instead of manufactures 338 lbs
If this is correct, then one needs to jump around on these tables to match
the Pr and weight.
Am I looking at this correctly?
Thank you,
