Q.1 The critical bending compressive stress in the extreme fibre of a structural steel section is 1000 MPa. It is given that the yield strength of the steel is 250 MPa, width of flange is 250 mm and thickness of flange is 15 mm. As per the provisions of IS: 800-2007. the non-dimensional slenderness ratio of the steel cross-section is    [2019 : 2 Marks, Set-ll]

(b) 0.75
(c) 0.25
(d) 2.0
Ans. (A)
Solution:


Q.2 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    [2019 : 1 Mark, Set-ll]

(c) same for both the members
(d) not specified in the Code
Ans. (A)
Solution:
As per IS 800 : 2007
