Geometry

A finite element model for each story is generated from a subset of the members in the full model. The finite element model of a single story is thus comprised of:

  • All the slab decks defined as two way,
  • Slab decks from one way region but only if they occur with two way slab deck within a slab edge loop,
  • All the beams on the story,
  • All the walls in the model that are located within one story above or below the current story,
  • All the columns up to the levels at which they are braced above and below the current story.

Note that RAM Concrete Gravity Analysis does not currently consider braces in the gravity finite element model that is created for any story. The presence of braces is considered in RAM Frame, and hence their affect is considered when determining forces on concrete members due to lateral loads. The gravity forces calculated in this mode are combined with the lateral forces in each of the Concrete Beam and Concrete Column Design Modes.
