futa in ACI 318-08 1

[VitoPito]

Hi,

I posted this in the fastener forum but realised that perhaps this forum would be more appropriate - apologies for the double post.

I was wondering how to go about finding the correct value for Futa in D.5.1.2 ACI 318-08. I intend to use A307 bolts with Fnt = 310MPa, which I am aware is not the yield strength, Fya, as used in the code above.

Does anyone know how to find the value of Fya, and in turn, Futa?

Any advice would be much appreciated.

The PCA Notes on ACI 318 have these values for common bolting materials.
