Analysis, design, and Code check of embedded retaining walls. The types of walls available are the following: · Generic material. · Concrete slurry, reinforced by panels. · Reinforced concrete secant piles. · Mini piles. · Steel sheet piles. Different types of support elements (active and passive anchors, struts, floor slabs, etc) can be introduced. The analysis is non-linear, considering an elasto-plastic behaviour for the soil and the support elements. Seismic action can also be accounted for and a check of global stability is carried out (failure planes).
