I have modeled a floor slab with a downstand beam that intersects a continuous column. How can I prevent the slab from resting on the column, but on the downstand beam only?


To ensure that the floor only rests on the downstand beam in this situation (Figure 01), it is recommended to model a minimum opening within the floor surface, see Figure 02.

Figure 02 - Surface with Opening

In order to keep the members or the lines of the members integrated into the surface, you can apply the "Connect Lines/Members" function subsequently to the entire model at once. Thus, it is ensured that the floor slab is still on the downstand beams.
