General dialog
Used to specify the section dimensions and properties for a general polygonal user defined table section.
| Setting | Description |
|---|---|
| Section Name | Type a section name used to identify the shape in the table. |
| Define Profile Polygon | Check this option to define polygon vertices by Z and X coordinates in the following table.
You also have the option compute the section properties for the shape automatically. |
| AX | Cross section area |
| D | Depth of the section |
| TD | Thickness associated with section element parallel to depth (usually web). To be used to check depth/thickness ratio |
| B | Width of the section |
| TB | Thickness associated with section element parallel to flange. To be used to check width/thickness ratio |
| IZ | Moment of inertia about local z-axis (usually strong axis) |
| IY | Moment of inertia about local y-axis |
| IX | Torsional constant |
| SZ | Section modulus about local z-axis |
| SY | Section modulus about local y-axis |
| AY | Shear area in local y-axis. |
| AZ | Shear area in local z-axis. |
| PZ | Plastic modulus about local z-axis |
| PY | Plastic modulus about local y-axis |
| HSS | Warping constant for lateral torsional buckling calculations |
| DEE | Depth of web. For rolled sections, distance between fillets should be provided |
Note: Properties
PZ,
PY,
HSS, and
DEE must be provided for code checking or member
selection per plastic and limit state based codes (AISC LRFD, British, French,
German and Scandinavian codes). For codes based on allowable stress design
(AISC-ASD, AASHTO, Indian codes), zero values may be provided for these
properties.
