Plan irregularity in an existing building leads to

  • A.a reduction in the total seismic force that the building attracts from the shaking
  • B.an increase in the natural period of the building which is generally beneficial
  • C.uniform distribution of the storey shear between all the resisting elements present
  • D.torsional response that overloads the far corners

Answer: D

Separation between the centres of mass and stiffness twists the building about a vertical axis, and the elements furthest from the centre of rotation take far more than their nominal share. Adding stiffness on the flexible side is the usual correction.
