New retaining wall calculation introduced in the July 2023 Engineering Library update which is tailored for designing common substructures. The calculation can be used to design any basement wall, from a small residential basement to a multi-storey underground parking garage. This calculation considers common basement wall conditions that the standard Retaining wall analysis & design (EN1992/EN1996/EN1997) calculation does not. This includes axial and moment loading from the superstructure, lateral wind loading on the exposed wall, a single or double layer of stem reinforcement, and a pinned or fixed support condition at the base of the stem. This calculation also includes the features available in the standard Retaining wall analysis & design (EN1992/EN1996/EN1997) calculation, such as determining soil loads and design of a supporting strip footing.

• The basement wall may be subject to vertical loads and moments from the structure above (dead, live, live roof, snow & wind). It may also be subject to surcharge loads (permanent and variable) applied to the top of the retained soil, lateral earth pressures and wind loads.

• The basement wall may be subject to additional vertical loads and moments at an intermediate support should an intermediate slab be defined.

• In accordance with EN1992, EN1997 and the national annex for the UK, Ireland, Singapore, Malaysia, Finland, Sweden, Norway or the recommended Eurocode values.
