a. The battery rack furnished shall be certified for seismic
zone [ ,] such that the battery can perform its intended
function during and after a seismic event.
Include the following paragraph if equipment structures are intended to be completely self-supporting (except
b. Design equipment and equipment supports to withstand and
maintain their structural integrity when exposed to seismic
loading indicated above. The equipment structures shall be
completely self supporting.
c. Support design shall not include friction for resisting the lateral
d. The maximum stresses, under seismic loading combined with all
other load effects, shall be within the normal allowable material
working stress limits as set forth in the appropriate references
listed in this specification.
e. Investigate any deformations resulting from the combined
influence of normal-operating loads and seismic loads, to verify
they will not impair structural integrity.
Demonstration of integrity. Demonstrate the equipment's ability to
withstand and maintain its structural integrity when subjected to the
forces resulting from the seismic conditions specified. This shall be
accomplished in one or a combination of the following methods:
a. Predict the equipment's performance and response to a seismic
force by mathematical static analysis;
b. Test the equipment under simulated seismic conditions (static or
dynamic testing); and/or
c. Utilize previous seismic certification of the equipment [or
equivalent equipment if equivalence can be shown,] and
demonstrate applicability under the seismic conditions specified.
The following subparagraph reflects seismic requirements under the Uniform Building Code (ICBO UBC.) Revise
as required under other building code jurisdictions.
Seismic loading method. The seismic loading on the equipment and
its supports shall be obtained by multiplying the weight of the
components by the horizontal seismic acceleration coefficient (H) in
accordance with the following three options. The force shall be
assumed to act in any lateral direction, combined with 0.15 W uplift
