User interface (UI) structural engineering is a sub-discipline of information architecture in which practitioners are trained to assess and ensure the integrity and durability of an application’s structural design or existing  UI structure.

UI structural engineers ensure that user interfaces are designed and built to be resilient to withstand information load and prevent unintended outcomes (i.e., poor usability, information gap/leakage, user harm, etc.) due to poor conceptual integrity. Consideration is given to the durability of UI components and the risk of component erosion that can impair performance over time.

The models provided by a UI structural engineer (or information architect) are integrated with those of other designers, such as UI and UX designers, and technical and non-technical architects.
