The April 2023 Engineering Library update introduced a new calculation which is tailored specifically for designing common substructures. The Retaining Basement Wall analysis & design (ACI 318) calculation can be used to design any basement wall, from a small residential basement to a multi-story underground parking garage. This calculation considers common basement wall conditions that the standard Retaining wall analysis & design 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.
