A post is a main vertical or leaning support in a structure similar to a column or pillar, the term post generally refers to a timber but may be metal or stone.[1][2][3][4][5][6][7] A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace. In the U.K. a strut may be very similar to a post but not carry a beam.[8] In wood construction posts normally land on a sill, but in rare types of buildings the post may continue through to the foundation called an interrupted sill or into the ground called earthfast, post in ground, or posthole construction. A post is also a fundamental element in a fence. The terms "jack" and "cripple" are used with shortened studs and rafters but not posts, except in the specialized vocabulary of shoring.
Timber framing
Timber framing is a general term for building with wooden posts and beams. The term post is the namesake of other general names for timber framing such as post-and-beam, post-and-girt construction and more specific types of timber framing such as Post and lintel, post-frame, post in ground, and ridge-post construction. In roof construction such as king post, queen post, and crown post framing. A round post is often called a pole or mast depending on its diameter thus pole building framing, or a mast church.
