SEISMIC MOTION-DAMPER FOR UPSTANDING ELECTRICAL EQUIPMENT

摘要

A seismic damper device is provided between the supporting plate adjacent the bottom of an upstanding piece of electrical apparatus and the lower main frame support members, supporting said upstanding electrical equipment, so that any relative motion between the upstanding column structure and the main lower-disposed frame support structure is restricted. Preferably, a liquid-filled dash-pot assembly, or energy-absorbing device, is utilized at one or more locations extending between the lower supporting plate member of each upstanding column structure and the lower-disposed main supporting framework.
