How is differential settlement modeled within SAFE?

Extended Question: The ACI Manual of Concrete indicates that uniform loading will cause greater deflection toward the center of slabs. To model this effect, ACI recommends minimizing soil stiffness at the slab center, and maximizing stiffness at the edges. Can SAFE model this condition?

Answer: Differential settlement may be modeled and calculated within SAFE by using multiple slab areas, and then by applying soil supports to each area of the foundation according to recommendations from the soil report or the geotechnical engineer. Properties typically vary along the surface of the slab, with greater stiffness values toward the perimeter. An overview of this topic is presented in the CSI Watch & Learn videos which follow:
