Minimum Bolt Diameter

[joelperez]

King Regards,
Does anybody know what's the minimum bolt diameter permitted by AISC due to environment extreme conditions?

 

[GC_Hopi]

Are you referring to providing sacrificial thickness (sacrificial bolt diameter in this case) to accommodate extreme environmental conditions.

 

[joelperez]

Hi GC Hopi, yes, that's what I'm talking about.

For nautical applications, it's 1" diameter but that is a federal specification requirement.

I don't believe AISC addresses this, I think they (AISC) are more of the opinion that structural bolts need to be protected from corrosion with paint or with hot dip galvanizing where applicable.
