A307 vs. F1554-36 -- AISC vs. ACI
A307 vs. F1554-36 -- AISC vs. ACI
(OP)
A co-worker used Apendix D to figure the shear of an F1554-36 1"diam. anchor rod (13.7kips) . I used the single shear value of an A307 in the AISC tables (9.42kips).
I realize that these anchors aren't technically the same, but for this shear/structural discussion should we be getting the same, or at least closer, results? I think the tensile strength differences between the bolts are 58ksi & 60ksi. Thats only a 4% difference, but our individual findings are MUCH further apart.
Thanks.

ACI -- 13.7kips
AISC -- 15.9kips
still a bit of a difference.
RE: A307 vs. F1554-36 -- AISC vs. ACI
Table 7-1 assumes the nominal bolt area is 0.785in^2. This is bigger than the "effective area" of the 1" dia bolt used for calculation in ACI(.606in^2).
That could account for difference in my opinion.

This discusses ACI vs AISC methods with regards to tension - shear is much the same.
