Abstract:
Various codes, specifications, and reports provide different requirements/recommendations for anchor bolt (rod) installation in foundations. The article discusses the issues related to these requirements/recommendations and encourages designers to add 2 in. (50 mm) to the calculated design embedment length and to specify the elevation of the top of the anchor bolt.
