challenges in recent application of base isolation technique in hospitals

As iran is located in one of the most seismically active regions, the design and construction of hospitals should consider the need to be operational during and after strong earthquakes for post-disaster rescue purposes. keeping performance of io (immediate occupancy) for structural and nonstructural elements during earthquake is very challenging, which is not often achievable through conventional systems. one of the techniques that has been shown thatis able to improve the performance level of both structural and nonstructural components of the building with sufficient reliability is base isolation system (naeim, 1999).
