For electrical equipment restraint, design in accordance with the applicable provisions in IEEE 693, or Section 13.3 of ASCE 7 whichever produces the more adverse seismic effects. For ASCE 7, use a spectral acceleration SDS = 0.247, IP = 1.50, and z/h=1. For IEEE 693, use a seismic qualification level of high.

iii. Requirements for Equipment Certification

iv. Definitions

Undercut anchor. Undercut concrete anchors are bearing-type anchors designed to be installed in cured concrete in a hole with a conical undercut near its blind end.

Expansive anchor. Expansive concrete anchors are designed to be installed in cured concrete in a straight hole. Anchorage relies on an torque-controlled expansion wedge and the friction developed between the drilled hole and the expanded wedge.

Adhesive anchor. Adhesive concrete anchors are designed to be installed in cured concrete in a straight hole drilled with a roto-impact drill, consistent with the manufacturers printed installation instructions and the applicable ESR report. Anchorage relies on a chemical adhesive bond to the threaded rod and to the concrete.

v. Concrete Anchors

Furnish all concrete anchors details and other materials and accessories required for seismic restraint of equipment.

General Requirements for Fasteners to Concrete

Compute anchor capacity as per Chapter 17 of ACI 318 and reduce the anchor capacity to account for the effect of spacing between the anchor bolts and the distance between anchor bolt and the nearest concrete edge. Provide anchor test data in accordance with ICC ES Evaluation Services Reports (ESR) for each type and class of concrete anchor verifying the suitability of an anchor for the intended application. For all post-installed anchors, select anchors suitable for use in cracked concrete and under seismic loading.

Floor Mounted Equipment

Provide anchor detail for floor mounted equipment to concrete that is reinforced and integrally connected to the reinforced concrete structure. Intermittent tension developed due to laterally applied seismic force of 1000 pounds (lbs) or less may be resisted with expansive concrete anchors capable of resisting dynamic loading in cracked and un-cracked concrete. Resist intermittent tension developed due to laterally applied seismic force greater than 1000 lbs with undercut concrete anchors.
