An external load whose line of action is parallel but does not coincide with the centroidal axis of the component/structure on which load is applied is known as an eccentric load. Whereas, the perpendicular distance between the centroidal axis and line of action of the load is known as eccentricity.

To achieve greater economy in material use, web-tapered steel members, where deeper cross-sections are used within the regions subjected to larger internal forces, are commonly employed within steel structures. However, the methods provided in current structural steel design specifications for the instability assessment of web-tapered steel members are based largely on those developed for prismatic

The three most common types of structural members are the W-shape (wide flange), the S-shape (American Standard I-beam), and the C-shape (American Standard channel). These three types are identified by the nominal depth, in inches, along the web and the weight per foot of length, in pounds. As an example, a W 12 x 27
