PEMB - Anchor Bolt Jargon
PEMB - Anchor Bolt Jargon
(OP)
I have a set of sealed shop drawings for small steel canopy.
The PEMB engineer has provided column loading data. Our loads are small. The greatest one is 3 kips uplift; and less than 0.5 kip horizontal.
Since we designed the slab, I still want to put into the Hilti software to doublecheck.
Below is what the PEMB engineer has provided for anchor bolts.
Does anyone know what 'Bend Length' is? Embedment? (a reference to older "L-Bolts" versus hex head?)
See below:

Thank you in advance.

-[EOR SHALL CONFIRM] THREADED ROD SHALL CONFORM TO ASTM [A307, GRADE A | F1554, GRADE 55 S1 | CSA G40.21-300W].
-ANCHOR RODS SHALL BE SET BY MEANS OF A TEMPLATE.
-EOR TO CONFIRM ANCHOR RODS ARE ‘L’ TYPE, WITH A LENGTH OF 1’-4”, A 3” HOOK, AND A THREADED 4” PROJECTION WITH A HEAVY HEX HEAD NUT AND WASHER TOP. EMBEDMENT SHALL BE 1’-0”.
If you use A307, make sure you spec that it has to be weldable.
Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

I agree with ya'lls comments....I think the PEMB Engineer is saying he wants 3" on the outstanding leg of the bolt; and that he wants a 2.5" projection out of the slab for the bolt.
The PEMB is not saying anything about embedment or anchor design, which will be my responsibility.
As a sidenote: I'm fine with the 'L-bolts', but I thought research had shown you get the same breakout and pullout capacity from bolts with an embedded hex head.

Embedment is usually by the foundation engineer. PEMBs tend to give diameter, quantity and pattern but not embedment.
Projection is distance from finish floor to top of anchor bolt.
They probably still reference hooked bolts because PEMB anchor bolts typically are not highly stressed.
