Standard Guide for Selection, Design, and Installation of Dimension Stone Anchoring Systems
SCOPE
1.1 This guide covers the categories of anchors and anchoring systems and discusses the design principles to be considered in selecting anchors or systems that will resist gravity loads and applied loads.
1.2 This guide sets forth basic requirements for the design of stone anchorage and provides a practical checklist of those design considerations.
1.3 This guide pertains to:
1.3.1 The anchoring of stone panels directly to the building structure for support,
1.3.2 The anchoring of stone panels to subframes or to curtainwall components after these support systems are attached to the building structure,
1.3.3 The anchoring of stone panels to subframes or to curtainwall components with stone cladding preassembled before these support systems are attached to the building structure, and
1.3.4 The supervision and inspection of fabrication and installation of the above.
1.4 Observe all applicable regulations, specific recommendations of the manufacturers, and standards governing interfacing work.
1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (See Tables 1 and 2.)

superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Natural building stone is chosen as a building’s cladding for its beauty which endures with minimal
maintenance. Stone is durable when used properly. Exercising good judgment when selecting the
particular stone, determining the quarrying and fabrication techniques, designing the method of
attachment, and installing all components correctly maximizes these benefits. A properly executed
stonecladdingisdesignedandinstalledwithinthecapabilitiesandlimitationsofthestoneandsupport
system to resist all forces that work on them.
This guide presents design principles that require consideration when designing anchorages and
evaluating exterior stone to be compatible with its proposed use. It is an overview of current
techniques and a review of minimum requirements for sound stone engineering and construction. The
guide does not list all possible methods of attachment nor does it provide a step-by-step procedure for
stone anchor engineering. Knowledge gained from new engineering designs, testing of applications,
and the investigation of existing problems are continually reviewed to update this guide. Comment
from users is encouraged.
Good judgment by architects, engineers, and contractors when specifying, designing, engineering,
and constructing stone and other work that interfaces stone is necessary to use this guide. Users of this
guide should combine known performance characteristics of the stone, the building’s structural
behavior, and knowledge of materials and construction methods with proven engineering practice.
