A two-span (10m each), continuous girder with solid cross section (0.1m by 0.6m) is modeled three times using frame, shell, and solid objects, as shown in Figure 1. The system is subjected to a unit moving load which travels the length of the structure. Section cuts are defined through the midspan of the second span. Section-cut forces are evaluated through influence-based moving-load analysis, which is run both with and without saving section cut forces.
