Post-and-lintel system , in building construction , a system in which two upright members, the posts, hold up a third member, the lintel, laid horizontally across their top surfaces. All structural openings have evolved from this system, which is seen in pure form only in colonnades and in framed structures, because the posts of doors, windows, ceilings, and roofs normally form part of the wall. The lintel must bear loads that rest on it as well as its own load without deforming or breaking. Brick or stone, weak in tensile strength inelastic and brittle , can provide only a short lintel; steel can be used for long lintels. Masonry lintels, depending on the cohesiveness of mortar, are especially weak; therefore, in masonry construction, lintels of monolithic single slab stone, wood, and stronger materials are used. The posts must support the lintel and its loads without crushing or buckling.

Post and Lintel

In architecture , post and lintel also called prop and lintel or a trabeated system is a building system where strong horizontal elements are held up by strong vertical elements with large spaces between them. This is usually used to hold up a roof, creating a largely open space beneath, for whatever use the building is designed. The horizontal elements are called by a variety of names including lintel , header, architrave or beam, and the supporting vertical elements may be called columns , pillars , or posts. The use of wider elements at the top of the post, called capitals , to help spread the load, is common to many traditions. The trabeated system is a fundamental principle of Neolithic architecture , ancient Indian architecture , ancient Greek architecture and ancient Egyptian architecture.
