Dimensions and properties for each shape are listed sequentially in a single row. The data in each column is as follows:
| Column in Database[a] | Variable | Description[a] |
|---|---|---|
| A | Type | Shape type: W, M, S, HP, C, MC, L, WT, MT, ST, 2L, HSS, PIPE |
| B (CG) | EDI_STD_ Nomenclature | The shape designation according to the AISC Naming Convention for Structural Steel Products for Use in Electronic Data Interchange (EDI), June 25, 2001. This information is intended solely for the use of software developers to facilitate the electronic labeling of shape-specific data and electronic transfer of that data. |
| C (CH) | AISC_ Manual_ Label | The shape designation as seen in the AISC Steel Construction Manual, 16th 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 specified in the AISC Naming Convention for Structural Steel Products for Use in Electronic Data Interchange (EDI), June 25, 2001. |
| D D | T_F T_F | 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.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.
