- Trussed-Braced Upright Frame
Upright frames having two columns similar to the chords of a truss with diagonal and horizontal bracing attached to and located between the columns. The diagonals and horizontals become the web members of the truss (referred to as a vertical truss).
- Unbraced Length
Distance between braced points of a member, measured between the centers of gravity of the bracing members.
- Vertical Impact Load
Additional downward force added to the beams produced during loading of the rack.
- Yield Point
First stress in a material at which an increase in strain occurs, without an increase in stress, as defined by ASTM.
- Yield Strength
Stress at which a material exhibits a specified limiting deviation from the proportionality of stress to strain, as defined by ASTM.
