TR.19.1 Wide Flange
General Format
For steel wide flange shapes:
property-spec = AX D TW WF TF IZ IY IX AY AZ (WF1) (TF1)
For composite wide flange shapes:
property-spec = -AX D TW WF TF IZ IY IX AY AZ (WF1) (TF1)
CFR CFL CFT MR
For composite wide flange shapes with bottom cover plate:
property-spec = -AX D TW WF TF IZ IY IX AY AZ (WF1) (TF1)
-CFR CFL CFT MR
BPR BPL BPT
- AX
- Cross section area
- D
- Depth of the section
- TW
- Thickness of web
- WF
- Width of the top flange (or both flanges when WF1 is not specified)
- TF
- Thickness of top flange (or both flanges when WF1 is not specified)
- IZ
- Moment of inertia about local z-axis (usually strong axis)
- IY
- Moment of inertia about local y-axis
- IX
- Torsional constant
- AY
- Shear area in local y-axis. If zero, shear deformation is ignored in the analysis.
- AZ
- Shear area in local z-axis. If zero, shear deformation is ignored in the analysis.
- WF1
- (Optional) Width of the bottom flange. The width of the top flange will be used if this value is not specified.
- TF1
- (Optional) Thickness of bottom flange. The thickness of the top flange will be used if this value is not specified.
The following option parameters are used to include a composite concrete slab. If included, these must be on a separate line following a dash, -, on the line containing the required section parameters.
- CFR
- Width of the composite slab to the right of the web center line
- CFL
- Width of the composite slab to the left of the web center line
- CFT
- Thickness of the composite slab
- MR
- Modular ratio of the concrete in the composite slab
The following option parameters are used to include a bottom flange cover plate.
