A new device of reduction for seismic response using friction force was developed. In this paper, vibration analysis of a small base isolation system using the device was investigated by excitation experiment using artificial seismic waves. Peak acceleration amplitude on the base isolation system has decreased to 43 90% compared to input waves. And root mean square (RMS) amplitude has decreased...

The baseline design concept for a seismic isolation component of the proposed “Advanced LIGO” detector upgrade has been developed with proofof-principle experiments and with computer models. It consists of a two-stage in-vacuum active isolation platform that is supported by an external hydraulic actuation stage. Construction is underway for prototype testing of a full-scale preliminary design.

A simplified method for the seismic design of low-rise, base-isolated shear wall structures is proposed in MOC-2012. This simplified method is basically a hybrid method, where the design of the isolation system is a simpler version for the static method available in US guidelines for the design of base-isolated structures and the design of the superstructure essentially is an improved version o...

Seismic hazards remained as a challenge to engineers over ages. In order to reduce loss of life and damage to property due to earthquake, several techniques have been developed among which Seismic Isolation technique using Elastomeric Isolators has gained high acceptance and becoming popular all over the world, due to its simplicity, reliability and overall cost effectiveness. Seismic Isolation...

The seismic response of bridges seismically isolated by lead-rubber bearings (LRB) to earthquake excitations of different magnitudes is presented in this thesis. The force-deformation behavior of LRB is considered as bilinear. The specific purpose of the study is to assess the effect of seismic isolation on the peak response of bridges subjected to different base accelerations ranging from 0.05...
