I am design the anchor bolts for a pre-engineered metal building. 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.
