Strength of Bolts PCI 7th Edition vs. AISC
Strength of Bolts PCI 7th Edition vs. AISC
(OP)
Hello,
I have a design that requires bolts capable of withstanding 50kips (service) in pure tension. I looked at A307 bolts. My background is in the precast industry, so I first looked at the attached table from PCI. When I looked at AISC(14th) Table 7-2 I see that the LRFD values are identical to the loads listed in PCI but the ASD loads in the steel manual are almost 13% higher than what PCI published. Any reason why PCI used an Ω factor of 2.25 while AISC only uses 2.0? What's really strange to me is that PCI names AISC 13th edition as the source for the attached table. I think the 13th edition uses 2.0 also, correct?

The bolt tensile capacity values are unchanged between AISC 13th to 14th.
