A seismic band added to an existing masonry building serves to

  • A.reduce the thickness of wall required to resist out-of-plane shaking
  • B.provide a decorative feature at lintel level around the building
  • C.tie the walls together so that they act as a box
  • D.increase the vertical load carried by the walls and so their frictional resistance

Answer: C

Correct answer: tie the walls together so that they act as a box

An unreinforced masonry building fails when its walls separate at the corners and each is left to resist out-of-plane shaking alone. A continuous band at lintel and eaves level ties them into a closed box, so the walls parallel to the shaking support those perpendicular to it. It is the single most effective measure for such buildings.
