SAP2000 calculates section-cut forces by summing the forces which act on member joints within the group of frame, shell, and link objects which define the section cut. During summation, the forces and moments at joint locations are transformed into equivalent conditions at a point of summation. They are then transformed into the local coordinate system which is specified for the reporting of section-cut forces. Section cuts may be defined by group, by cutting plane, or within the graphical user interface.
