      S.No. SHORT COLUMNS LONG COLUMNS 1 If the ratio of effective length to its least lateral dimension is less than or equal to 12 or (l/b ≤ 12). If the ratio of the effective length of the column to its least lateral dimension is greater than 12 or (l/b > 12). 2 The effective length to least radiusRead more

      1 If the ratio of effective length to its least lateral dimension is less than or equal to 12 or (l/b ≤ 12). If the ratio of the effective length of the column to its least lateral dimension is greater than 12 or (l/b > 12).
      2 The effective length to least radius of gyration ratio is less than or equal to 40 or (l/k ≤ 40). The effective length to least radius of gyration ratio is greater than 40 or (l/k > 40).
      3 Buckling tendency is very low. Long and cylinder columns buckle easily.
      4 Very high crushing tendency. Very low crushing tendency.
      5 The load-carrying capacity is high. The load-carrying capacity is less.
      6 It has more radius of gyration. It has less radius of gyration.
      7 The failure due to their crushing. failure due to their buckling.
      8 It has a high load-carrying capacity. It has less load carrying capacity.
      9 Subjected to compressive stresses. Subjected to buckling stresses.
      10 Its slenderness ratio is less than 45 or S < 45. Its slenderness ratio is more than 45 or S > 45.
      11 It has a large lateral dimension as compared to its height. It has a small lateral dimension as compared to its height.
      12 It is stronger than a long column and it is highly preferred. It is weaker than a short column and generally, it is not preferable.
