Abstract: 
Waste of valuable natural resources and high death toll in recent strong earthquakes has led to revise seismic codes in the earthquake prone countries. The same is true for Iran as one of the most seismically active countries in the world that three revisions have been applied to its seismic code so far. Since Bam earthquake, the seismic assessment for the existing buildings has become a major issue for the construction engineering. In this regard a research has been carried out to assess seismic performance of a nine story reinforced concrete building. Nonlinear static analysis was conducted using procedures recommended in the rehabilitation provisions and results indicated that a large number of frames in both directions exceed life safety performance levels. Base isolation by lead rubber bearing adopted as alternative to retrofit entire building and it caused isolated structure support target displacement without failure on desired safety level.
