What is the maximum slenderness ratio for a steel member carrying compressive loads resulting from dead loads and imposed loads?

What is the maximum slenderness ratio for a steel member carrying compressive loads resulting from dead loads and imposed loads? Correct Answer 180

Type of member

Maximum slenderness ratio

A member carrying compressive loads resulting from the dead load and the imposed load

180

A tension member in which a reversal of direct stress occurs due to loads other than wind and seismic forces

180

A member subjected to compression force resulting only from combination with wind/earthquake actions, provided the deformation of such members 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 as a tie in a roof truss or a bracing system not considered effective when subjected to a possible reversal of stress into compression resulting from the action of wind earthquake forces.

350

Member always under tension (other than pre-tensioned members)

400
