Study on seismic isolation system for long-period ground motion

open access: yesNihon Kikai Gakkai ronbunshu, 2015
In this paper, the authors have developed a new type of horizontal seismic isolation system which has large effect of vibration isolation for ordinary earthquakes and suppresses the resonance of the isolation system due to long-period ground motions ...

Structural Health Monitoring of a Unidirectional Isolation Bridge: Bidirectional Seismic Behavior, Stochastic Model Updating, and Prediction

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...

Seismically Isolating a Structure: A Rational Approach for Feasibility Assessment and Definition of Basic Parameters

open access: yesEng
Although conceptually simple, the application of seismic isolation can pose dangerous pitfalls. It is based on decoupling the dynamic response of a structure from the ground motion by inserting isolation devices at its base.
