Ratio of the effective height of a member to its effective thickness.

The ratio of effective length or height of a wall or column to effective thickness; used as a means of assessing the stability of a masonry wall or column.

The effective length of a member divided by the appropriate radius of gyration.

The comparison of the length to the thickness of a structural piece so that the stiffness of that piece may be determined, since stiffness is relative to length and thickness.

(1) The ratio of a member's effective height to radius of gyration. (2) The ratio of a member's height to thickness.
