EXECUTION
3.1
BRACING
**************************************************************************
NOTE: Designs must include complete seismic details
showing bracing requirements. The design is for the
supports of the equipment, not the equipment itself.
Bracing does not guarantee that the equipment is
rugged enough to survive earthquake shaking. When a
piece of equipment is required to remain operational
after an earthquake, the manufacturer should be
consulted regarding the capabilities of the
equipment to withstand seismic loading.
