DaveViking thanks for your reply to my "concrete embedments" query but I was unable to open up your full reply. Can you help. Thanks philiph (UK)
The website must've got hung up when you were trying to access it perhaps? Can you open other posts? What were the symptoms? Try this URL directly:
thread167-13082 that doesn't work, you should notify the webmaster.
Basically, get yourself a copy of ACI AB-81, "Guide to the Design of Anchor Bolts and Other Steel Embedments" to supplement the other ACI codes.
