conventional methods for seismic design of structures are based on building capacity. because of the disadvantages of conventional methods, base isolation system  is known as an effective solution to protect structures against earthquakes. in this study the operation of 2-storey steel frame with and without seismic isolators under near-fault earthquake of chichi، northridge and  capemendocine  ...

Seismic isolation is a method to reduce the destructive effects of earthquakes on a structure in which the structure is separated from its foundation by devices called seismic isolators. As a result, the horizontal movements of the earthquake transmitted to the structure are reduced. The seismic isolation is used for both newly constructed structures as well as for retrofitting the existing bui...

Recent earthquakes have enforced the engineering community to design seismically more efficient buildings through energy dissipation systems. For this purpose, paper investigates seismic behavior of a high-rise building with series base isolation Firstly, 20-storey steel frame is selected as fixed-base building, and then equipped lead rubber bearings (LRBs). In modelling LRB, period alternative...
