Seismic isolation apparatus

The Journal of the Acoustical Society of America, 1999
A seismic isolation apparatus which has a composite multilayered member comprising a plurality of hard plates having rigidity and a plurality of soft plates having viscoelastic property which are arranged to form alternating layers between an upper flange and a lower flange; and satisfies the condition that the proper vibration to the horizontal ...

SEISMIC ISOLATION OF BRIDGES

Natural and Technological Risks. Building Safety, 2020
Мосты, и в особенности мосты большепролетные, являются уязвимыми при воздействии землетрясений и получают серьезные по­вреждения, а иногда и разрушаются при сильных землетрясениях. Сейсмоизолирующие устройства позволяют существенно осла­бить воздействия землетрясений на мосты.

Seismic Isolation and Decrease of Seismic Effects on Bridges

2013
A planned road bridge in an active seismic zone near the city of Žilina in Slovakia was analysed for seismic effects. The seismic analysis has shown that an inelastic structural response due to a strong earthquake is very likely. Because of these large seismic design forces an increase of foundation dimensions was necessary. An alternative solution has

New Structural Seismic Isolation System

2018
New structural seismic isolation system named Spherical Foundation Structural Seismic Isolation (SFSSI) system which has been discovered and first prototyped on a 104 m height (26 storey) building example is presented. Creation of SFSSI system aimed to build structural seismic isolation system, of which period must be more than the predominant period ...

SILER Project: Design of the Seismic Isolators

Volume 8: Seismic Engineering, 2014
This paper describes the SILER (Seismic-Initiated event risk mitigation in LEad-cooled Reactors) Project results obtained so far in the design of the seismic isolation system of two nuclear power plants: the ELSY configuration for the LFR (Lead-Cooled Fast Reactor) design and the MYRRHA configuration for the accelerator-driven systems (ADS).

TESTING OF SEISMIC ISOLATORS

Seismic isolation has a significant worldwide application in which most currently used isolators are in the form of lead-rubber bearings and friction pendulum bearings of the single, double, and triple concave configurations. The behavior of these isolators is affected by frictional heating or heating of the lead core.
