systems in buildings that have a performance objective higher than
life-safety, the drawings shall be stamped by the registered
engineer who stamps the calculations required above.
SD-03 Product Data

Equipment Requirements[; G][; G, [_____]]
Copies of the design calculations with the detail drawings.
Calculations shall be stamped by a registered engineer and shall
verify the capability of structural members to which bracing is
attached for carrying the load from the brace.

EQUIPMENT REQUIREMENTS
1.4.1
Rigidly Mounted Equipment
**************************************************************************
NOTE: Rigidly mounted equipment is defined as
having a period of vibration of 0.06 seconds or less
for the equipment plus its mounting. Equipment with
a fundamental period greater than 0.06 seconds
should be assumed to be flexibly mounted or
nonrigid. The designer may allow a reduction to the
design seismic forces applied to ground-mounted
equipment when properly justified in the
calculations. List items that may require
additional reinforcements (internally) to prevent
permanent deformation, dislocations, separation of
components, or other damage, which would render the
equipment inoperative for significant periods of
time following an earthquake and to meet the
specified requirements. Coordinate with note in
paragraph BRACING.
**************************************************************************
The following specific items of equipment: [_____] to be furnished under
this contract shall be constructed and assembled to withstand the seismic
forces specified in TI 809-04, Chapter 10. For any rigid equipment which
is rigidly attached on both sides of a building expansion joint, flexible
joints for piping, electrical conduit, etc., that are capable of
accommodating displacements equal to the full width of the joint in both
orthogonal directions, shall be provided.
1.4.2
Nonrigid or Flexibly-Mounted Equipment
**************************************************************************
NOTE: The appropriate lateral force coefficient for
nonrigid or flexibly-mounted equipment, should be
calculated and inserted in the blank space.
**************************************************************************
The following specific items of equipment to be furnished: [_____] shall
be constructed and assembled to resist a horizontal lateral force of
[_____] times the operating weight of the equipment at the vertical center
of gravity of the equipment.
