A structure designed for a 100 year event over a 50 year life has an encounter probability of roughly

  • A.40 per cent
  • B.1 per cent
  • C.2 per cent
  • D.99 per cent

Answer: A

One minus 0.99 raised to the fiftieth power gives about forty per cent. Return period is therefore a poor guide to the risk over a structure's whole life. Encounter probability is the honest measure. A fifty year life sees the hundred year event often enough.
