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 ...

An innovative hybrid control building system of multiple isolation and connection is proposed and investigated using both time history and input energy responses for various types of ground motions together with transfer functions. It is concerned that the seismic displacement response at the base-isolation layer of the existing baseisolated buildings may extremely increase under long-period an...

The concept and theory of base isolation system are widely accepted at the present. To accomplish the predicted behaviours of the base-isolated buildings, the design for base isolation system is regarded as the dominant factor of the success of isolated buildings. Although the base isolation design can be fulfilled using Uniform Building Code 1997, conceptual design is yet necessarily analyzing...

The most important property of a base-isolation system is to make the base more flexible than the elements of the superstructure, but it must still be stiff enough to resist typical pounding forces, wind loadings, and similar low-amplitude horizontal forces. However, the potential consequences of earthquake-induced poundings on seismically isolated buildings can be much more substantial, and, t...

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 structural control can provide the potential protection through passive and active control techniques. Structures with base isolations have been successfully implemented and proven effective in the vibration mitigation. To enhance the functionality of base isolations, a hybrid control system can be considered using a combination with active control devices. This research applies the hybrid ...

Earthquakes are one of the natural hazards that occur due to sudden violent movement of earth’s surface which releases energy and has destructive power in many parts of the world. The development of recent technologies for the control of seismic hazards catches the attention of structural engineers to make the structures seismically resistant. The seismic base isolation technique is a passive p...
