This research reveals the efficiency of seismic isolation system in the form of rubber-metal supports with different height buildings at multi component seismic impact. As an example, seismically insulated monolithic reinforced concrete 5, 9 and 16 story buildings are considered. The solution of the problem is obtained by a direct integration of the motion equations for an explicit scheme in fi...

This paper reports on an investigation into how base isolation can produce benefits for the architectural design of hospitals. If a relatively new technology such as base isolation can be coupled with interdisciplinary collaboration from the birth of a project, it seems possible to achieve an improvement not only in their seismic, but also in their architectural design. The methodology adopted ...

Recent studies have highlighted the potential benefits of inelastic foundation response during seismic shaking. According to an emerging seismic design scheme, termed rocking isolation, the foundation is intentionally under-designed to promote rocking and limit the inertia transmitted to the structure. Such reversal of capacity design may improve the seismic performance, drastically increasing ...

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...
