increase storage efficiencies by eliminating interferences with
dual structural systems, Frazier provided petitioner a storage
rack system with increased structural capabilities. This
enhanced structural rack system provides the support for the roof
over the racks and for the east wall adjacent to the racks.
These increased structural capabilities were accomplished by
increasing the size of the vertical columns, increasing the
amount of diagonal bracing on the end panels of the racks, and
providing rigid connections where the shelves meet the support
posts. Frazier also provided additional cross members at the
roof to support the metal roof panels and additional supports to
connect with the other structural elements.
Approximately 80 percent of the ground floor of the Reserve
Facility is occupied by 19 rows of floor-to-ceiling storage
racks, which are 446 feet long by 176 feet wide by 50 feet high,
running north to south.5 A typical rack row has vertical columns
or posts 4 feet 8 inches from front to back (width) and 10 feet 2
inches apart (length). Each row of racks is separated from the
next by an aisle which is 5 feet wide. The rack posts consist of
steel channel posts with a C-shaped cross section. In some
locations, at the lower end of a rack post, the channel section
is made stronger by welding two channels together to form a
rectangular cylinder. The upper and lower portions of each rack
5Eighteen of the rows of racks are double-loaded.
