To do this, there is an option in the "Combination Expressions" tab when activating automatic combinations that allows you to activate the favorably acting permanent loads.
Question
How can I consider loads from the self-weight as "favorable" and "unfavorable" for the combinations?

For design objects, you can optionally display sags or extreme results.

Do you work with the structural components consisting of slabs? In that case, you have to perform the shear force design with the requirements of punching shear design, for example, according to 6.4, EN 1992‑1‑1. In addition to floor slabs, you can also design foundation slabs in this way.
In the Ultimate Configuration for concrete design, you can define the punching design parameters for the selected nodes.

The results of solid stresses can be displayed as colored 3D points in the finite elements.

Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:
- Vertical walls
- Flat roofs
- Monopitch roofs
- Duopitch/troughed roofs
- Vertical walls with duopitch roof
- Vertical walls with flat/monopitch roof
The following standards are available to you:
-
EN 1991-1-4 (including National Annexes)
-
ASCE 7
-
CTE DB-SE-AE
-
