A member of a common form of truss, as a roof truss. It is strictly a tie, intended to prevent the sagging of the tiebeam in the middle. If there are struts, supporting the main rafters, they often bear upon the foot of the king-post. Called also crown-post.
A compression member which, together with suitable bracing wires, limits the deflection of a major member (such as a spar) which has to resist bending loads. King-posts raised above the wings of early flying boats were used to reinforce the interplane bracing.
A vertical post extending from a tie-beam to the apex of the roof, usually supporting a ridge purlin. (Wood, Margaret. The English Medieval House, 412) Related terms: Queen-Post
