RAM Concept loads are applied to the highest priority slab or beam they intersect. Analytical iTwin loads are applied to a single Analytical iTwin member. When pushing loads to Analytical iTwin, RAM Concept must determine which single Analytical iTwin member the load should be applied to. RAM Concept may have to split line or area loads that straddle more than one Analytical iTwin member.

A RAM Concept Point Load is applied to an Analytical iTwin beam if it lies on the beam centerline. Otherwise, it is applied to the surface member whose effective shape contains the point.

A RAM Concept Line Load that is completely contained in the beam centerline is applied to that beam. Otherwise, the line load is trimmed to the effective shape of each Analytical iTwin surface member it intersects. If the line load intersects more than one surface member or has a disjoint intersection with a single surface member, it is split into shorter line loads and applied to the surface members they overlap.

RAM Concept area loads are trimmed to the outer boundary of the effective shapes of all Analytical iTwin surface members that they intersect. If the intersection is disjoint, the RAM Concept area load is split into smaller polygonal area loads and applied to the surface members they overlap.

It is possible to create a RAM Concept model in a way that makes it impossible for RAM Concept to maintain the accuracy of both the RAM Concept and Analytical iTwin models. For example, consider a RAM Concept slab containing an opening and a second slab inside the hole (an island). RAM Concept maintains the user's intentions by creating an Analytical iTwin surface member for each slab. If there is an area load covering both slabs, RAM Concept must create an additional area load for the island slab. However, the larger RAM Concept area load will still cover the island slab, so the next Update operation would create yet another area load on the island slab. Instead, RAM Concept does not create a new area load for the island slab and will leave the Analytical iTwin surface member unloaded. The preferred method for modeling this configuration is to split up the larger area load so that it does not overlap the island slab.
