The forces acting at a Section Cut are based on the RAM Frame analysis results. The forces acting on each segment of the Section Cut are first determined by integrating the wall stresses determined from the RAM Frame finite element analysis along the entire segment. Next, the forces acting at each segment are resolved at the geometric center of the Section Cut to form a single set of globally-oriented forces (see Figure below).

The Section Cut forces are calculated for each load case that was considered in the most recent RAM Frame analysis. From this, combined loads are calculated using the load combinations selected by the user in the RAM Concrete Wall module. The RAM Concrete Wall module deals solely with combined loads and does not consider individual load cases. The resulting array of combined loads at each Section Cut is used for the design checks.
