Performance evaluation of seismically isolated buildings near active faults

This paper investigates the collapse risk of seismically isolated buildings that are designed by procedures ASCE/SEI 7-16 standard for sites within 5 km active fault controls hazard. The study is based on six-story perimeter frame with special concentrically braced frames a location in California. seismic isolation systems considered this comprised either: (i) triple friction pendulum bearings high coefficients at sliding interfaces, (ii) low coefficient surfaces and enhanced fluid viscous dampers, or (iii) surfaces. demonstrates per Section 17.3.3 standard, but either increased isolator displacement capacity superstructure strength comparison to minimum required, can achieve an acceptable risk. It also demonstrated have best performance far-field motions not necessarily near-field pulse-like ground motions.
