Modern Steel Construction
Do you know what type of shape these designations refer to and where I can find information about the geometric properties?
AB designations refer to the American Bridge Company, which fabricated shapes called “Constant Dimension Columns” designedby the American Bridge Company (see Figure 1).
These columns are not rolled columns but rather were created by combining plate
and angles. Milo Ketchum’s Structural Engineers’ Handbook, which provides a list of section sizes, including the three shape designations you provided as an example, in Table 162.
The properties provided include the size of the web plate and four angles used to create the constant dimension columns, the weight, the strong and weak axis section modulus, and the radius of gyration.
