Seismic Behaviour of Base-Isolated Buildings: A State-of-the Art Review.

Influence of isolator characteristics on the response of base-isolated structures

“…Seismic isolation, which is now recognized as a mature and efficient technology, can be adopted to improve the seismic performance of strategically important buildings such as schools, hospitals, industrial structures etc., in addition to the places where sensitive equipments are intended to protect from hazardous effects during earthquake [1][2][3]. Based on the extent of control to be achieved over the seismic response, the choice of the isolation system varies and thereupon its design is done to suit the requirements of use of the structure.…”

Seismic response of base-isolated structures during impact with adjacent structures

“…Since the inception of novel idea of base isolation, variety of isolation devices have been developed and implemented in real-life projects for aseismic design of structures [1,2]. However, with the addition of flexible layer at foundation level the peak base displacements increase significantly during earthquakes and the structure can collide upon adjacent structures like boundary retaining walls, entrance ramps, etc.…”

Earthquake response of isolated elevated liquid storage steel tanks

“…Since the forces transmitted to the superstructure have been largely reduced, the superstructure can usually be expected to be linearly elastic, even under the excitation of severe earthquakes. The base isolation techniques have been developed and successfully implemented in buildings and bridges [6][7][8]. For ground supported isolated liquid storage tanks, the dynamic responses were investigated and it was found that the base isolation is also effective in reducing the earthquake response.…”
