According to Indian Standard IS 800, the maximum allowable slenderness ratio should not exceed the values given: Type of Member Slenderness ratio ● A member carrying compressive loads resulting from dead and superimposed loads = 180 ● A member subjected to compressive loads resulting from wind/earthquake forces = 250 provided the deformation of such members does not adversely affect the stress in any part of the structure. ● A member normally carrying tension but subjected to reversal of stress due to wind = 350 or earthquake forces. ● Tension member (other than pre-tensioned member) = 400
