Ductility in the context of seismic design means the ability of a structure to

  • A.carry a very large load while deforming almost not at all
  • B.return exactly to its original shape after any level of shaking
  • C.transmit the whole of the ground acceleration to its occupants unchanged
  • D.deform well beyond its elastic limit without losing much strength

Answer: D

A ductile structure absorbs energy over many cycles of large deformation, which is how it survives an earthquake that exceeds its elastic strength. Brittle behaviour, by contrast, means failure follows very soon after the elastic limit is passed, leaving no reserve.
