(b) The manufacturer shall provide Evaluation Service Reports (ESRs) for each anchor to the building owner.
(c) Metal used in adhesive anchors shall be austenitic stainless steel.
3.1.7.4 Installation Documentation. When adhesive anchors are used
(a) a training record signed by the installers and by the trainer shall be provided to the building owner, and shall state that the installers were trained in accordance with manufacturer’s published instructions for installation. A copy of the published instructions for installation shall be attached.
(b) a certification record by an independent inspector stating that the adhesive anchors were installed in accordance with the manufacturer’s published instructions for installation shall be provided to the owner. The inspector’s credentials listing training and experience shall be attached.
3.1.7.5 Inspections, Tests, Operation, and Maintenance. The adhesive anchors shall be tested in general accordance with ASTM E488-03, Standard Test Method for Strength of Anchors in Concrete and Masonry, and at a proof load of not less than 55% of their rated ultimate capacity nor more than 65% of their rated ultimate capacity.
3.1.7.5.1 Initial Tests for Adhesive Anchors
(a) All adhesive anchors shall be tested for the integrity of the installed anchor in the field prior to use.
(b) The initial installation tests shall be performed by trained, experienced persons who are independent from the installer.
(c) The testing procedure and the results of the test shall be certified by a registered professional engineer. The test shall be to ensure anchor integrity and shall not be tests for shock, energy, or other lifeline loads.
3.1.7.5.2 Maintenance Inspections and Tests
(a) All adhesive anchor assemblies shall be tested in the field at intervals not to exceed 5 yr.
(b) The test procedure and results of the test shall be certified by a registered professional engineer. The test shall be to ensure anchor integrity and shall not be tests for shock, energy, or other lifeline loads.
3.1.8 Load-Rating and Weight Identification
3.1.8.1 Each suspended unit of an equipment installation shall be provided with a conspicuously located load-rating plate, stating the weight of the unit and load rating of the suspended unit.
3.1.8.2 Davits, outriggers, TLGs, trolleys, and carriages shall have a conspicuously located load-rating plate, stating the equipment’s load rating, and the weight of the unit.
Additionally, there shall be special consideration for installations in hurricane areas that may have supplementary wind and debris and/or seismic building code jurisdictional requirements.
3.2.3 Allowable Deflections. The deflections of all structural components and connections shall be limited so as not to adversely affect the safe operation of any portion of the equipment and shall not exceed those specified in the standards referred to in para. 3.1.1.
The calculated deflection of any structure or component shall not induce stresses greater than permitted by this Standard.
3.2.4 Wind Loads. Suspended or supported units, carriages, supporting structures, and operating mechanisms shall be designed and constructed to withstand the following wind loads applied in the least favorable direction:
(a) Those parts of the equipment and installation that remain in place, exposed to the wind when not in service, shall be designed for forces produced by storm winds. Wind velocity shall be taken as not less than 75 mph (33.6 mIs) at 30 ft (9.1 m) above grade and shall be adjusted for the height of the equipment and for local conditions including seismic and wind loads as determined by the local building code jurisdiction. There shall be special consideration for installations in hurricane areas that may have additional wind and debris building requirements.
Velocity pressures shall be corrected for member shape and shielding effects. In lieu of exact analysis, the equipment and installation may be designed for a wind pressure of 40 psf (1 915 Pa) for the first 200 ft (61 m) of elevation plus 3.5 psI (167.6 Pa) for each additional 100 ft (30.5 m) above 200 ft (61 m) applied to the projected area.
(b) All parts of the equipment and installation exposed to wind during operation shall be designed for wind forces produced by winds of 50 mph (22 mIs) for all elevations. Velocity pressures shall be corrected for member shape and shielding effects. In lieu of exact analysis, the equipment and installation may be designed for a wind pressure of 10 psf (480 Pa) applied to the projected area for all elevations.
(c) All values specified are minimum and shall be adjusted upward, when necessary, to meet local conditions.
3.2.5 Projected Exposed Area (Exterior Installations). The exposed area subjected to wind pressure shall be the total area of all portions of the equipment exposed to wind pressure.
