Q. A steel column is restrained against both translation and rotation at one end and is restrained only against rotation but free to translate at the other end. Theoretical and design (IS:800- 2007) values, respectively, of effective length factor of the column are
(A) 1.0 and 1.0
(B) 1.2 and 1.0
(C) 1.2 and 1.2
(D) 1.0 and 1.2
Ans:
As per IS:800-2007
Theoretical effective length = L
Design effective length = 1.2L
