A building has adequate strength but excessive drift. The appropriate retrofit is to

  • A.add stiffness or damping
  • B.add strength to every column and beam throughout the height of the building
  • C.reduce the strength of the existing frame so that it yields earlier in the response
  • D.leave the building alone

Answer: A

Drift is a stiffness problem, and it is corrected by stiffening the structure or by damping the response rather than by adding capacity that is already sufficient. Diagnosing which quantity is deficient is what the assessment is for.
