According to IS 800: 2007, what will be the maximum slender ratio of a member (beam) carrying compressive load resulting from dead load and imposed load ?

According to IS 800: 2007, what will be the maximum slender ratio of a member (beam) carrying compressive load resulting from dead load and imposed load ?

Right Answer is:

180

SOLUTION

As per IS 800:2007

Member Max. effective slenderness ratio 
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 the 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 a 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

The maximum slender ratio of a member (beam) carrying compressive load resulting from dead load and imposed load will be 180.
