Webb5 jan. 2024 · Tutorial. A truss is a structure that consists of a collection of structural elements connected at pin joints or nodes. In theory, the pin joints provide no rotational resistance and behave as hinges. In practice, this is not always the case. The benefit of a truss is that the members are predominantly axially loaded.
