The large displacement that occurs across an isolation layer must be accommodated by

  • A.a seismic gap or moat around the building at ground level
  • B.additional reinforcement placed in the columns of the superstructure above
  • C.increasing the mass of the isolated superstructure
  • D.reducing the vertical load on the isolators

Answer: A

Displacements of a few hundred millimetres are normal, and every service entering the building, every stair and every surrounding pavement has to allow for them. Failing to maintain that gap is the most common way an isolation system is defeated in service.
