Contracting Officer or designated representative (CODR). Each

LUKE AFB - App A - Page 6 column shall have openings to readily accommodate beam connectors, end-to-end, at corresponding heights through 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 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. The width of the column, facing the aisle, shall be a minimum 3 inches.

3.2.2.2. BEARING PLATES

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.

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 (REV 1)

Shelf beams shall be the box or step type. Any openings in the shelf beam construction shall face inward, they shall not face the aisle. The connector shall not be welded to the column.

Shelf beam-to-column connection shall be of the locking type.

With a uniformly distributed load of 6000lb per bay, there shall be no permanent deformations, and elastic deflections shall not exceed 0.56 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

LUKE AFB - App A - Page 7

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 be adjustable, allowing the 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 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 design as the opening.

3.2.4. ROW SPACERS (REV 1)

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 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.

3.2.5. LEVELING SHIMS

The shims shall have holes corresponding to the holes in the bearing plate, and shall anchor or lock with the bearing plate when the rack 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.

3.2.6. ANCHORING THE STRUCTURE

LUKE AFB - App A - Page 8

The rack system shall be anchored to resist all design shear and uplift forces. The rack units shall be designed to be a rigid freestanding structure and shall not be connected to any existing building structure.

3.2.7. ASSEMBLY

The assembled pallet rack system shall be rigid, stable, and without deformation or skewing when each bay is loaded to the capacity of the design loads. The pallet rack 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 rack system.

3.2.8. DECKING

Wire mesh decking shall be installed in all bays between all parallel shelf beams as shown of AF Drawing ALK906-01. The decking shall be heavy duty welded steel wire with integral support channels capable of supporting a uniformly distributed load of 1100 pounds per bay. 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

0.56 percent of the unsupported span. Decking shall be R-Mark compliant. The decking shall be plated or galvanized to protect against corrosion. 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.
