The basic objective of seismic design as stated in IS 1893 is that a structure should

  • A.resist minor shaking undamaged and severe shaking without collapse
  • B.remain entirely undamaged under the most severe shaking ever expected at the site
  • C.collapse in a controlled manner whenever any earthquake shaking occurs at all
  • D.be designed for wind loading only

Answer: A

The objective has three levels: minor shaking should leave the structure undamaged, moderate shaking may cause repairable damage to non-structural elements, and severe shaking may damage the structure heavily provided it does not collapse. Designing for no damage at all under the severest shaking would be prohibitively expensive and is not what the code asks for.
