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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
