Title: Shallow Embedded Anchors

Author(s): Werner Fuchs and Jan Hofmann

Publication: Concrete International

Volume: 39

Issue: 2

Appears on pages(s): 45-53

Keywords: nonstructural, cover, redundant, reinforcement

DOI: 10.14359/51689626

Abstract:
Although ACI 318-14 provides design requirements for anchors in concrete, it does not apply to specialty inserts used for anchoring nonstructural elements. Background information is provided on the ACI 318 design procedure, shallow anchors and related parameters are discussed, and modification factors are proposed for ACI 318 design values.
