Question

14.A laced column 10 m long is carrying a factored axial load of 1000 KN. 3 points
The column is restrained in position but not in direction at both the ends.
Two ISMC 250 @298.2 N/m (rzz = 99,4 mm, ryy= 23.8 mm) are placed
back-to-back in a distance such that slenderness ratio about both the
direction becomes
equal. The effective length of the laced column will be:
a. 10 m
b. 10.5 m
O c. 11.0 m
O d. 12.5 m​

Answer 1

Answer:

14.A laced column 10 m long is carrying a factored axial load of 1000 KN. 3 points

The column is restrained in position but not in direction at both the ends.

Two ISMC 250 @298.2 N/m (rzz = 99,4 mm, ryy= 23.8 mm) are placed

back-to-back in a distance such that slenderness ratio about both the

direction becomes

equal. The effective length of the laced column will be:

a. 10 m

b. 10.5 m

O c. 11.0 m

O d. 12.5 m
