Specify Loading Requirements
Floor loading is not usually an issue in nonraised floor installations. The
information presented here is directed toward raised floor installations.
Raised Floor Loading
Raised floor loading is a function of the manufacturer’s load specification
and the positioning of the equipment relative to the raised floor grid.
While Hewlett-Packard cannot assume responsibility for determining
the suitability of a particular raised floor system, it does provide
information and illustrations for the customer or local agencies to
determine installation requirements.
Floor loading terms used to describe floor loading issues are described in
the following table:
Table 6
Term Definition
Dead load The weight of the raised panel floor system, including the
understructure. Expressed in lb/ft2 (kg/m2).
Live load The load that the floor system can safely support. Expressed in lb/ft2
(kg/m2).
Concentrated load The load that a floor panel can support on a 1-in2 (6.45cm2) area at the
panel’s weakest point (typically the center of the panel), without the
surface of the panel deflecting more than a predetermined amount.
Ultimate load The maximum load (per floor panel) that the floor system can support
without failure (expressed by floor panel(s) breaking or bending).
Ultimate load is usually stated as load per floor panel.
Rolling load The load a floor panel can support (without failure) when a wheel of a
specified diameter and width is rolled across the panel.
Average floor load Computed by dividing the total equipment weight by the area of its
footprint. This value is expressed in lb/ft2 (kg/m2). The average floor
load for a maximally-configured HP rp7400 cabinet is approximately
215.5 lb/ft2.
