Shallow Embedded Anchors
ACI 318-14, Chapter 17, provides design requirements for anchors in concrete used to transmit structural loads between: 1. Connected structural elements; or 2. Safety-related attachments and structural elements. Provided that they are used correctly, these provisions result in safe and economical solutions for fastenings and connections. However, Chapter 17 provisions are restricted to the design of structural anchors. In fact, the Commentary to the Code explicitly states that specialty inserts -- devices that include those used for anchoring nonstructural elements -- are "not within the scope of this Code." Modern buildings require the installation of cable trays, fire sprinklers, air conditioning equipment, and pipes. The installations frequently are made using shallow fastenings consisting of an individual anchor or groups of two or four anchors embedded in the concrete cover. This means that significant loads are carried by anchors that are embedded in the zone between the reinforcement and the outer surface of reinforced or post-tensioned concrete slabs, precast hollow core concrete slabs, or concrete slabs on metal decks.
