Q: The effective length of a steel compression member depends on:
  • A. Rotational boundary conditions at its ends
  • B. Translation boundary conditions at its ends
  • C. Rotational and translation boundary conditions at its ends
  • D. Its slenderness ratio
Correct Answer: Option C - The effective length of a steel compression member depends upon end restrained condition (rotational and relative translational condition). • A restrained should be of sufficient strength and stiffness to forbid movement of the restrained portion.
C. The effective length of a steel compression member depends upon end restrained condition (rotational and relative translational condition). • A restrained should be of sufficient strength and stiffness to forbid movement of the restrained portion.

Explanations:

The effective length of a steel compression member depends upon end restrained condition (rotational and relative translational condition). • A restrained should be of sufficient strength and stiffness to forbid movement of the restrained portion.
