c. Utilize previous seismic qualification of the equipment and

demonstrate applicability under the seismic conditions specified

herein.

ATTENTION:

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

3.2.4.3

its supports shall be obtained by multiplying the weight of

components by the horizontal seismic acceleration coefficient. The

force shall be assumed to act in any lateral direction.

3.2.4.4

Friction. Support design shall not include friction in resisting the

lateral shear load.

3.2.4.5

Maximum stresses. 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 design standards and codes listed in this specification.

3.2.4.6

Deformation. Deformations resulting from the combined influence of

normal operating loads and seismic loads shall be investigated to

verify that they will not impair structural integrity.

Review documents. Provide for review, upon request, all

3.2.4.7

calculations and test results utilized for seismic qualification of the

UPS, its support structures, and any anchors. Said documents shall

be signed and sealed by a registered professional engineer.

Operating environment. Each UPS and associated equipment shall meet the

3.2.5

performance requirements of this specification while operating under the

environmental conditions specified below. Any environmental effects on the life

expectancy of the UPS shall be clearly identified by Seller in appendix A.
