The maximum effective slenderness ratio of steel members always in tension (other than pre-tensioned members) is ______.

Correct option is A

Maximum slenderness ratio for tension member are :
→ Member always under tension( other then pre-tensioned member) slenderness ratio is equal to 400
→ A tension member in which a reversal of direct stress occurs due to loads other than wind or seismic force is equal to 180.
