AISC Shapes Database v15.0 is an update to Shapes Database v14.1. This version is consistent with shape properties and dimensions tabulated in the AISC
Steel Construction Manual, 15th Edition, 1st Printing. The database contains some additional section properties that are not included in the Manual.

EDI_ STD_
Nomenclature
The shape designation according to the AISC Naming Convention for Stru ctural Steel Products for Use in Electronic Data
Interchange (EDI), June 25, 2001. This information is intended solely for the use of softwa re developers to facilitate the
electronic labeling of shape-specific data and electronic transfer of that data.
AISC_
Manual_ Label
The shape designation as seen in the AISC Steel Construction Manual , 15th Edition. The exception to this is the designation
for double angles. There is a separate listing (row) for each back-to-back spacing and configuration. Therefore, the shape
designation reflects these two variables. The listings for double angles follow the convention spec ified in the AISC Naming
Convention for Structural Steel Products for Use in Electronic Data Interchange (EDI) , June 25, 2001.
Boolean variable. A true, T, value indicates that there is a special note for that shape (see below). A false, F, value indicates
that there are no special notes for that shape.
Special notes:
W-shapes: a value of T for: tf > 2 in.
M-shapes: a value of T indicates that the shape has sloped flanges.
WT-shapes: a value of T for: tf > 2 in
MT-shapes: a value of T indicates that the shape has sloped flanges.
