A structural member designed to carry loads between or beyond points of support. The orientation of the member (being horizontal, vertical or sloped) is not relevant to its definition (contrary to a beam or column). A member represents a linear structural element from an architectural or structural modeling point of view and shall be used if it cannot be expressed more specifically as either a beam or a column. It can also simply be an architectural element which is non-load bearing.
Undefined truss member
An undefined truss member is a linear structural member within a truss or girder that cannot be defined as a truss chord, truss strut or truss tie(brace).
