- Design Stress
Design strength divided by the appropriate section property, such as section modulus or cross section area
- Diagonal Bracing
Inclined structural member carrying primarily axial force in a braced frame.
- Distortional Buckling
A mode of buckling involving change in cross-sectional shape, excluding local buckling.
- Effective Length
Length of an otherwise identical column with the same strength, analyzed with pinned end conditions.
- Effective Length Factor
Ratio between the effective length and the unbraced length of the member.
- Effective Section Modulus
Section modulus reduced to account for buckling of slender compression elements.
- Effective Width
Reduced width of a plate or slab with an assumed uniform stress distribution, producing the same effect on the behavior of a structural member as the actual plate or slab width, with its non-uniform stress distribution.
- Factored Load
Product of a load factor and the nominal load
- Flexural Buckling
Buckling mode in which a compression member deflects laterally without twist or change in cross-sectional shape.
- Flexural-Torsional Buckling
Buckling mode in which a compression member bends and twists simultaneously without change in cross-sectional shape.
Resultant distribution of stress over a prescribed area.
- Gravity Load
Loads, both dead and live, acting in the downward direction
