Overview

SAP2000 calculates the section cut forces by summing the element joint forces from the frame, shell and link members included in the group that defines the section cut. The joints that are considered are those at the same location as the point objects that are included in the group. To sum the forces, each considered joint force and moment is transformed to the location that the forces are summed about and then they are transformed to the local coordinate system specified for the section cut forces. When all of the considered forces have been transformed to the appropriate location and coordinate system they are simply summed up and the total forces are reported.
