Question

I would like to extend an existing structure with a false ceiling that is not connected to the existing columns. How can I model it?

Answer

There is one way of how you can implement your project to achieve a result. Our existing structure is deformed without a false ceiling as follows.

Figure 01 - Previous Modeling

We use the existing structure and the drag & drop function as well as copying the elements while holding down the CTRL key for quick modeling. It is important to ensure that the existing pinned connections are displayed correctly. In this example, only one workflow is to be displayed so that the connections between columns and slabs are modeled rigidly. The bottom columns are modeled as nodal supports by using the Column in Z ... function.

The false ceiling should not transfer any loads to the existing continuous columns.

To compare both models, you can evaluate the results by using two substructures modeled in a file.
