Ribbed Foundation

The Ribbed / Star Solution

Ribbed / star foundation as FEM model

The ribbed foundation solution consists of a thin slab, a pedestal/plinth in the center of the foundation and six to twelve arms that strengthen the slab. The saving is estimated up to 40% of the concrete volume.

The ribbed foundation is a variant to the classic gravity foundation. Important parts of the concrete volume are replaced by backfill.

As promising as the benefits of this interesting design may seem at a first glance: the complicated shatter works stands against the savings in concrete. That is why this solution shows his major advantages particularly when the costs for concrete are much higher than the labor costs. Technically, this solution work on grounds with poor soil stresses.
