General dialog
Used to specify the section dimensions and properties for a general polygonal user defined table section.
Section property fields:
Setting | Description |
---|---|
AX | Cross section area |
D | Largest dimension parallel to the local Y axis (overall section depth along Y). |
TD | Thickness associated with section element parallel to Y axis (taken to be the web). To be used to check depth/thickness ratio of the web. |
B | Largest dimension parallel to the local Z axis (overall section width along Z). |
TB | Thickness associated with section element parallel to Z axis (taken to be the flanges). To be used to check width/thickness ratio of the flanges. |
IZ | Moment of inertia about local z axis |
IY | Moment of inertia about local y axis |
IX | Torsional constant |
SZ | Section modulus about local z axis (about the local y-axis for Z up) |
SY | Section modulus about local y axis (about the local z axis for Z up) |
AY | Shear area in local y-axis (about the local z axis for Z up) |
AZ | Shear area in local z axis (about the local y-axis for Z up) |
PZ | Plastic modulus about local z axis (about the local y-axis for Z up) |
PY | Plastic modulus about local y axis (about the local z axis for Z up) |
HSS | Warping constant for lateral torsional buckling calculations |
DEE | Depth of web between the flanges. 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.
