AS 4084-1993 pdf free.Steel Storage Racking.Here is the introduction.
AS 4084 sets out minimum requirements for the design (in permissible stress method), fabrication and erection tolerances, test methods, operation and maintenance.
This Standard applies to adjustable static pallet racking made of cold-formed or hot-rolled steel structural members. It covers both the situation where racking is installed within a building and where the racking forms part of the building frame.
AS 4084 does not cover drive-in and drive-through racking, cantilever racking. mobile racking or racking made of materials other than steel.
1.3 IWFINITIONS For the purpose of this Standard, the definitions below apply.
1.3.1 Adjustable pallet racking—storage system comprising upright frames perpendicular to the aisles and independently adjustable, positive locking shelf beams, spanning between the frames parallel to the aisles, and designed to support unit loads (see Figures 1(a) to 1(c)).
1.3.2 Aisle width—space along which the unit load handling equipment operates (see Figure 2(a)).
1.3.3 Base plate—hearing plate bolted or welded to the underside of the column to transmit vertical and horizontal forces into the floor, and provide structural fastening of the upright frame to the floor.
1.3.4 Bay height—maximum vertical distance from the ground to the highest point of the unit load in a racking structure (see Figure 2(h)).
1.3.5 Bay width—see definition of shelf beam length (see Clause 1.3.24 and Figure 2(b)).
1.3.6 Ceiling clearance—minimum vertical distance between the highest part of the upright frame or the highest part of the unit load on the top shelf beam level and the underside of the ceiling or the support steelwork for the ceiling (see Figure 2(b)).
1.3.7 Closed-face racking—adjustable pallet racking where the unit loads are supported by the shelf beams (see Figure 1(h)).
1.3.8 Columns-—vertical members that comprise the upright frame and are subject to compressive forces parallel to their longitudinal axes and have provision for random attachment of shelf beams.
1.3.9 Column protector—component in front of the upright frame that is secured to either the floor or column, or both and designed to resist minor impact loads as specified in Clause 1.6.2 (see Figure 1(a)).
1.3.10 Column width—maximum horizontal distance of an upright frame column measured from flange to flange (outside).
1.3.11 Diagonal brace—diagonal member in the vertical plane to supplement horizontal braces to join columns together and form a trussed upright frame that is rigid and stable, and designed to withstand applied design loads (see Figure 1(b)).
1.3.12 Finished tolerance—tolerance of the unloaded racking after fabrication and erection prior to initial loading.AS 4084 pdf download.
