In many cases, the strips are made to marge, resulting in a mat foundation, as shown in Fig. 2. That is, the foundation consists of a solid reinforced concrete slab under the entire building. In structural action, such a mat is very similar to a flat slab or a flat plate, upside down, i. e., loaded upward by the bearing pressure and downward by ...
