T.1 Specifying member offsets
Member 2 (the beam) actually spans only the clear distance between the column faces rather than the center to center distance. This is modeled by specifying offsets.
MEMBER OFFSET 2 START 6.0 0.0 0.0 2 END -6.0 0.0 0.0
Select member 2 by clicking on it in the view window.
Note: If the beam cursor isn't currently active, select the Beam Cursor tool in the Selection group on the Geometry ribbon tab.
- Select the Specifications page on the Analytical Modeling page bar. The Specifications - Whole Structure dialog opens. Member releases, offsets, and other beam specifications are defined here.
- Click Beam.
Specify the member start offset:
- Select the Offset tab.
- Select Start as the Location.
6.0(in.) in the
X offset field.
Leave the Direction as Global. It is convenient to define the offset at the start node in the X direction. Since the beam member is aligned with the global X axis, there is no difference between choosing a global or local frame of reference.
- Click Assign.
