Answer 1

Explanation:

As per IS 800:2007, Table no. 3 , Maximum values of effective slenderness ratio:

Member	Maximum effective slenderness ratio (kL/r)
A member carrying compressive loads resulting from dead loads and imposed loads	180
A tension member in which a reversal of direct stress occurs due to loads other than wind or seismic forces	180
A member subjected to compression forces resulting only from combination with wind/earthquake actions, provided the deformation of such member does not adversely affect the stress in any part of the structure	250
Compression flange of a beam against lateral torsional buckling	300
A member normally acting m a tie in a roof truss or a bracing system not considered effective when subject to possible reversal of stress into compression resulting from the action of wind or earthquake forces	350
Members always under tension’) (other than pre-tensioned members)	400
