Tying the footings of a building together with plinth beams helps seismic performance by

  • A.allowing each footing to settle independently
  • B.eliminating the need for reinforcement in the columns
  • C.forcing the foundations to move together during shaking
  • D.reducing the total weight of the substructure

Answer: C

Differential horizontal movement between footings imposes large forces on the columns above, and tying them prevents it. The beams also shorten the effective column length, which is why their effect on column stiffness has to be recognised in the analysis.
