3.2.2.1. COLUMNS

The columns shall be a continuous channel, box channel, rectangular, square or other formation approved by the Contracting Officer‘s Technical Representative (COTR). The width of the column, facing the aisle, shall be nominal 1-7/8 inches. Each column shall have openings to readily accommodate beam connectors, end-to-end, at corresponding heights throughout the height range of the column openings. The openings at the bottom shall allow for the tops of shelf beams to be installed at six inches above the ground and shall continue upward to the top of the column by 2 or 3 inch increments. All openings of each column shall be identical to each other and identical to the openings of all other columns. The position of all corresponding openings of the columns shall not vary more than 3/32-inch as measured from the bottom of the bearing plates.

The arrangement of the openings and the fastening devices of the beams shall be such that the tops of the beams are flush, within 3/8-inch, with the top of the column.

3.2.2.2. BEARING PLATES

Shaw AFB, SC - App B - Page 3

The bottom of each column shall have a load bearing plate securely attached. Each bearing plate shall be sufficiently sized to disperse the maximum load imposed by the column. Each bearing plate shall have a minimum of two punched holes to accept minimum 3/8-inch anchor bolts in accordance with 3.2.6.

3.2.2.3. DIAGONAL/HORIZONTAL BRACING

The columns shall be braced by horizontal and diagonal braces.

Each end of all braces shall be securely welded to the columns.

The braces shall not protrude beyond the sides of the columns or obstruct the attachment of the shelf beams to the columns, at any height on the columns. The centerline of the bottom horizontal brace shall not be located more than 12 inches from the bottom of the upright frame, and the centerline of the top horizontal brace shall be located not farther than 12 inches from the top of the upright frame. Other diagonal and horizontal braces shall be uniformly spaced between the top and bottom horizontal braces.

3.2.3. SHELF BEAMS

Shelf beams shall be the closed box or step type. Any openings in the shelf beam construction shall face inward, they shall not face the aisle. Shelf beam-to-column connection shall be of the locking type. Each pair of shelf beams shall provide a bay width of 108 inches. With a uniformly distributed load of 1,100 pounds per bay, there shall be no permanent deflections, and elastic deformations shall not exceed 0.70 percent of the unsupported span, measured with respect to the two ends of the beam. Shelf beams shall be designed with a safety factor of

1.65 to 1.

3.2.3.1. CONNECTORS

Each end of the shelf beams shall have a multiple prong slip-fit or slip-joint type shelf beam-to-column connector. Separate shelf beams and connectors are unacceptable. The connectors shall allow shelf beams to be moved with no more than the use of a soft hammer. The connector shall be capable of transferring all loads and external forces of the shelf beam to the column without failure of the connection, or damage to the column or connector. The prongs shall be of sufficient number, size, and strength to withstand repeated loading and unloading of the rack, and to continually sustain the rated shelf beam load. The prongs shall engage with the openings of the columns in such a manner to prevent lateral rotation of the beam, with each prong contributing to the support of the beam. The prongs shall

Shaw AFB, SC - App B - Page 4 engage with the openings of the columns to ensure a snug metal-to-metal fit between the horizontal and vertical load carrying members. The prongs shall be of the same type design as the opening. The connector shall not be welded to the column.

3.2.4. WIRE MESH DECKING

Wire mesh decking shall be installed in between all parallel shelf beams and uprights for Types “B”, “F”, and “G” shelving.

Wire mesh decking shall be installed in between all parallel shelf beams and uprights except the bottom shelf for Type “G1” shelving. The decking shall have a nominal 2-inch by 4-inch grid. The decking shall be heavy duty welded steel wire with integral support channels capable of supporting a uniformly distributed load of 1,100 pounds per bay. Decking shall be R- Mark compliant. The decking shall be designed with a safety factor of 1.65 to 1. The decking shall not exhibit permanent deformation and elastic deformations shall not exceed 0.70 percent of the unsupported span. The decking shall be plated or galvanized to protect against corrosion in accordance with

3.3.3. of the Cover PD. Decking shall be the appropriate type to interface with the type shelf beam being provided. The ends of the wire mesh decking shall bend over the shelf beam to provide a secure load supporting deck and keep the decking from accidentally disengaging from the shelf beams.

3.2.5. TIRE SUPPORTS

Two tire support beams per bay shall be used to support the tires stored on type “G1” shelving in accordance with AF Drawing TSH804-06.

The supports shall be angle iron. The tire supports shall be easily removed and replaced from the wide span shelving. Tire supports shall be adjustable to accommodate a variety of tire diameters. Tire supports shall have the capability to be adjusted to any storage level configuration that the shelf beams will allow. Each pair of tire supports shall have a minimum load capacity of 1,100 pounds per bay. Tire supports shall be bolted or otherwise connected to front to back beams or as approved by the COTR (welding is unacceptable).

3.2.6. ROW SPACERS

Row spacers shall be capable of joining the backs of two upright frame sections together to form a double row arrangement. The row spacers shall provide a 6-inch flue space when storage locations are back-to-back. Each end shall firmly and securely attach to the column and prevent unintentional disengagement.

The row spacer shall be of sufficient size and strength to

Shaw AFB, SC - App B - Page 5 withstand all forces applied to the connected upright frames during normal loading and unloading operations without deformation or failure. The Contractor shall supply and install a minimum of 2 row spacers for each set of back-to-back frames.

The top row spacer shall be installed within 12 inches of the top of the frame. The bottom row spacer shall be installed within 12 inches of the bottom of the frame. The remaining row spacers shall be installed equidistant from each other.

3.2.7. LEVELING SHIMS

Leveling shims shall be installed with the shelving units where necessary. The shims shall have holes corresponding to the holes in the bearing plate, and shall anchor or lock with the bearing plate when the shelving is erected. Shims shall be equal in width and length to the bearing plate under which it is installed. Shims shall be of varying thickness so no more than five shims are installed at any point. Slotted shims shall be unacceptable.

3.2.8. ANCHORING THE STRUCTURE

The shelving shall be anchored to resist all design shear and uplift forces. The shelving units shall be designed to be a rigid freestanding structure and shall not be connected to any existing building structure except the floor. Each bearing plate shall be securely anchored to the floor with minimum one 3/8-inch diameter anchor bolt. The minimum embedment of the anchor shall be in accordance with 3.3.2.3 of the Cover PD.

3.2.9. ASSEMBLY

The assembled wide-span shelving system shall be rigid, stable, and without deformation or skewing when each wide-span shelving unit is loaded to the capacity of the design loads. The wide-span shelving system shall assemble so that the columns are perpendicular to the beams and parallel to each other. Shelf frames shall be straight and square. All horizontal members shall be level to within 1/8-inch per 10 feet measured over any distance in the shelving system.

4. QUALITY ASSURANCE PROVISIONS

4.1. INSPECTION

The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of this appendix and the Cover

Shaw AFB, SC - App B - Page 6

PD. These inspections shall be completed as part of the system checkout test and again as a part of the quality conformance test.

4.2. TESTS

The following tests shall be performed on the system as part of the system checkout test and again as a part of the quality conformance test.

No. Paragraph Description

1. 3.2.3. Three wide-span shelves, picked at random, shall each be loaded with 1,100-pounds to ensure the shelf beams are set in place. The loads shall then be removed. The distance from the top of each designated shelf beam to the top of the shelf beam above it shall be measured and recorded as M1. The 1,100-pounds shall then be put back onto the designated shelves. The loads shall be left for a minimum of four continuous hours. The distance from the designated shelf beams to the top of the next shelf beam shall be measured again and recorded as M2. The following formula shall be used to determine the deflection amount:

Deflection = [(M2 - M1) / shelf beam length] * 100

If the deflection is greater than 0.70 or if permanent deformation exists on either the shelf beams or decking when the loads are removed, the system shall fail.

4.3. CERTIFICATIONS
