Beam/Column with Multiple Cross-Sections: Use Replacement Profile
Some Column or Beam elements can use multiple cross-sections and/or several Building Materials:
•Multi-segment Beams or Columns
•Tapered Beams or Columns
•A single Complex Profile with different Profile Modifiers at each end
This Column or Beam generates a single 1D Member in the Structural Analytical Model, using the Replacement Profile.
You can see it represented in the Structural Analytical Model: turn on Show Profiles of Load-Bearing Cores (from the Structural Analytical Model toolbar).
1D Member of Multi-Segment Beam, with Single Load-Bearing Profile
The data of this Replacement Profile are used when exporting the 1D Member to analysis programs. The element’s Replacement Profile does not affect its physical model in ARCHICAD.
For each 1D element with a variety of cross-sections, you must choose a Replacement Profile in the element Settings dialog box:
Choose Replacement Profile
1.Go to the Structural Analytical Parameters panel of Beam or Column Settings.
2.If the element has a varied cross-section as described above: the Replacement Profile pop-up is available in the preview window.
3.Click to choose a structure for the Replacement Profile core: Rectangular, Circular, or Complex Profile
For a Complex Profile structure:
–Use the pop-up to choose a Profile and set editable parameters (if any). The pop-up includes Profiles which
-are available for Column or Beam (as applicable)
-include at least one core component
For a Rectangular or Circular structure:
–Use the pop-up to choose its Building Material and its dimensions
Override Alignment
By default, the replacement Profile's Origin is inserted at the Member's reference line.
If needed, you can realign the Profile Origin to better reflect the architectural model. Check the Override Alignment box, then choose a different anchor point:
For a Rectangular or Circular structure, the Member is adjusted to the structure's reference line by default. (Here too, you can override this alignment by choosing a different anchor point.)
