IS 13920 requires the ratio of the shorter to the longer cross-sectional dimension of a column to be not less than

  • A.0.1
  • B.0.4
  • C.0.04
  • D.1.0

Answer: B

A very elongated column behaves more like a wall in one direction and like a slender strut in the other, and confining it effectively becomes impractical. Keeping the two dimensions within a factor of two and a half of each other avoids that condition.
