Isection
This section type may be used to specify a generalized
I-shaped section. The cross-sectional properties required are listed
below. This facility can be utilized to specify tapered I-shapes.
1) DWW = Depth of section at start node.
2) TWW = Thickness of web.
3) DWW1 = Depth of section at end node.
4) BFF = Width of top flange.
5) TFF = Thickness of top flange.
6) BFF1 = Width of bottom flange.
7) TFF1 = Thickness of bottom flange.
8) AYF = Shear area for shear parallel to Y-axis.
9) AZF = Shear area for shear parallel to Z-axis.
10) XIF = Torsional constant ( IX or J).
