ABSTRACT:
Two energy dissipation devices, each comprising a first plate, a plurality of spaced tapered plates, a plurality of cylinders, a plurality of washers, and a base frame. The devices can absorb seismic energy through the yielding of the tapered plates and effectively reduce a building vibration response during an earthquake. The devices are particularly suitable for use in building structures that must be designed to dissipate a large amount of seismic energy to achieve economical earthquake-resistant construction.
