Match the period range with the quantity that governs the spectral ordinate.

1. Very short period   2. Intermediate period   3. Very long period

P. Ground displacement   Q. Ground acceleration   R. Ground velocity

  • A.1-Q, 2-R, 3-P
  • B.1-P, 2-Q, 3-R
  • C.1-R, 2-P, 3-Q
  • D.1-Q, 2-P, 3-R

Answer: A

The three regions of a spectrum are acceleration-sensitive, velocity-sensitive and displacement-sensitive in that order as the period grows. Recognising which region a structure sits in tells you which ground-motion measure controls its demand.
