For a column subjected to bending and compression, the maximum slenderness ratio as per IS 800:2007 is:
-
A.
180
-
B.
200
-
C.
300
-
D.
250
Correct Answer:
A. 180
Explanation:
The correct answer is 180.
According to Table 3 of IS 800:2007, the maximum effective slenderness ratio for a member subjected to compressive loads resulting from a combination of dead loads and imposed loads is 180. This limit also applies to tension members where a reversal of direct stress occurs due to loads other than wind or seismic forces. For columns, which are primary compression members, maintaining a slenderness ratio within this specified limit is essential to ensure structural stability and prevent premature buckling under service loads. Other limits include 250 for members acting under compression from wind or earthquake forces and 400 for members always in tension.
