If a column is having the following parameters,
Lex = Effective length in the x- direction
Ley= Effective length in the y- direction
B= Lateral dimension in x- direction
D= Lateral dimension in y- direction
What are the condition that the column is a short column?
(a) Lex/B <12
(b) Ley/D <12
(c) Both (a) and (b)
(d) None of these
Solution:
For a short column, as per cl. 25.1.2, pg. 41
< 12 and
< 12
Answer: 1. (c) Both (a) and (b)
