Sl. No. | Member | Maximum Effective Slenderness Ratio (KL/r) |
(i) | A member carrying compressive loads resulting from dead loads and imposed loads | 180 |
(ii) | A tension member in which a reversal of direct stress occurs due to loads other than wind or seismic forces | 180 |
(iii) | A member subjected to compression forces resulting only form combination with wind/earthquake actions provided the deformation of such member does not adversely affect the stress in any part of the structure. | 250 |
(iv) | Compression flange of a beam against lateral torsional buckling. | 300 |
(v) | A member normal acting as 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 |
(vi) | Members always under tension (other than pre-tensioned members) | 400 |
