M. To assign a tapered I section
To define and assign a web-tapered I section, use the following procedure.
Note:
f1 (Depth of section at start node) should always be greater than f3 (Depth of section at end node). You must provide the member incidences accordingly.
If the tapered section requires a composite slab, then use a tapered I Section user-provided table section instead.
Tapered I-sections have constant flange dimensions and a linearly varying web depth along the length of the member.
Shear deformation is not considered for tapered I-Beams and tapered poles. This means that the SET SHEAR command has no effect on the deformation computed for members with these cross sections.
-
On the
Specification ribbon tab, select the
Tapered tool in the
Beam Profiles group.
The Tapered I dialog opens. - Select an associated Material. This feature allows you to use material definitions for steel, stainless steel, concrete, aluminum, or any previously specified, custom material definitions.
- Specify the profile dimensions for the shape.
-
Either:
To… Do the following… add the section to the model for later assignment click Add. add the section to the model and assign to the current member selection click Asign. - Repeat steps 2 through 4 as needed to add more tapered I sections to the model.
- Click Close.
