Consolidation of Rigid Raft by the Program GEO Tools

In many practice cases, treating the raft as completely rigid is convenient. In this case, due the applied loads the raft will rotate as a rigid body. In a rigid body motion, the points on the rigid body move linearly. An analysis for the contact pressure under a rigid raft on isotopic elastic half-space medium was carried out by many authors. The oldest work for the analysis of foundation rigidity is that of Borowicka (1939). He analyzed the problem of distribution of contact stress under uniformly loaded strip and circular rigid foundation on semi-infinite elastic mass. A review about the methods of analysis of rigid rafts may be found in standards such as DIN 4018 or books as example Selvaduri (1979).
