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.
