The wall may retain soil or other granular material. It analyses the stability of the wall based on the loads and resistances and results in bearing pressure sliding overturning and rotational stabilities. Loads applied on the wall may consist of self weight soil pressure water pressure live and seismic loads. Resistances may consist of base friction and cohesion passive earth pressure other structures or a shear key. Load and resistance factor design (LRFD) mode can be applied. If the wall is a reinforced concrete structure the software also supports the reinforcement design.
