Richard, my experience (17 years) has been to require the metal building supplier to design the anchor bolts along with the rest of the building. Our specification (and the building department) requires that these calculations be prepared by a licensed California Civil Engineer. I have never received any complaints so this seems unusual, but it may be related to the location of your building. My work has been mostly in California. I use bolts with a standard hex head or nut embedded in the footing. If the bolt is not available as prefabricated stock they usually will use A36 rod. Joyce Fuss, S.E.

I have noticed in previous discussions that it appears the preference for anchor bolts is the use of a headed bolt verses a hooked bolt or a bolt with embedded plate. I do not have a good resource on anchor bolt design and I would like some comments on the following: What thickness of bolt head should be used? Is there a minimum projection width and height of the head or does an ordinary off the shelf A307 bolt work? Is there a minimum length of embedment in concrete you would suggest, regardless of what the calculations say? Is there a practical maximum length of embedment/bolt length for A307 which one could easily buy? I have designed buildings for almost 15 years now, including quite a few pre-engineered buildings. I have always required the building supplier to design the anchor bolts and never had much of a problem with that requirement. This particular building supplier is making a big fuss about having to design the anchor bolts, which includes embedment, etc. Have I been wrong to require the supplier to completely design the anchor bolts in the past? Prior to getting the calcs, I do not have firm numbers on reactions to design the bolts myself. Now, if I design the bolts and the contractor doesn't like it, does he have a legitimate claim for an extra? I look forward to your input on this. __________________________________________________ Richard Lewis, P.E.
