# Strands \[FEA] Strands define the prestressing strand properties used in tendon definitions and section reinforcement. Strand data can be imported from a database or manually defined. ## Properties **Diameter:** The nominal diameter of the prestressing strand. Common sizes include 0.5 inch (12.7 mm) and 0.6 inch (15.2 mm) for 7-wire strands. **Area:** The cross-sectional area of the prestressing strand. This is used in computing the total tendon area (# of Strands × Strand Area) and in sectional analysis tools such as moment capacity and interaction diagrams. **Weight:** The weight of the strand per unit length. Used for computing the self-weight contribution of the prestressing steel. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.openbrim.org/templates/openbrimfea/properties-fea/strands-fea.md?ask= ``` The question should be specific, self-contained, and written in natural language.
