In an arbitrary section, you can reduce all forces originating in a section to a point (the center of gravity of all elements in the section). The coordinate system in which reduced forces are displayed is a system resulting from the definition of a cut: n axis - the normal to the cut plane, axes 1 and 2 are positioned in the cut plane.
The results of force reduction are displayed in the table for stories on the Reduced forces tab. This tab displays the following values:
- Coordinates of the center of gravity of a section
- Vector components (1, 2, and the normal one to the cut plane)
- Values of reduced forces (forces N1 and N2 are in the section plane and the Nn force is a force normal to the section)
- Values of reduced moments
In addition, the drawing displays the position of the center of gravity of the section O to which forces are reduced and the system of a cut with the axes 1, 2 and n.
