The typical isolated period of a base-isolated building is of the order of

  • A.10 to 20 seconds
  • B.0.5 to 0.6 seconds
  • C.2 to 3 seconds
  • D.0.1 to 0.2 seconds

Answer: C

That range lies well down the descending branch of a design spectrum, where the acceleration ordinate is a fraction of its peak value. It is also long enough to be several times the fixed-base period of the building, which is what makes the isolation effective.
