WebApr 14, 2024 · In theory, the pin joints provide no rotational resistance and behave as hinges. The benefit of a truss is that the members are predominantly axially loaded. This means they are either in compression, tension or have no force, so-called zero force members. This makes trusses a particularly efficient structural form.
