IS 1893 assigns a response reduction factor of 5.0 to

  • A.an ordinary reinforced concrete shear wall system without ductile detailing
  • B.a special moment resisting reinforced concrete frame
  • C.an ordinary moment resisting reinforced concrete frame with no special detailing
  • D.a load bearing building in unreinforced masonry with no bands at all

Answer: B

A special frame is detailed to IS 13920 so that it can yield reliably at its beam ends, and it earns the highest factor available to reinforced concrete frames. An ordinary frame takes 3.0 and unreinforced masonry only 1.5, reflecting how little inelastic capacity each of them has.
