Q: In order to account for shear deformation effect, the ratio of effective slenderness ratio of laced columns to the actual slenderness ratio is
  • A. 1.0
  • B. 1.05
  • C. 1.25
  • D. 1.5
Correct Answer: Option B - The effective slenderness ratio of laced columns shall be taken as 1.05 times the actual maximum slenderness ratio, in order to account for shear deformation effects. • The slenderness ratio for lacing bars should not exceed 145.
B. The effective slenderness ratio of laced columns shall be taken as 1.05 times the actual maximum slenderness ratio, in order to account for shear deformation effects. • The slenderness ratio for lacing bars should not exceed 145.

Explanations:

The effective slenderness ratio of laced columns shall be taken as 1.05 times the actual maximum slenderness ratio, in order to account for shear deformation effects. • The slenderness ratio for lacing bars should not exceed 145.
