Post+and+lintel

Post and lintel is a construction technique in which lintels, or beams, are laid horizontally across the tops of posts or columns. The disadvantages of this type of construction are the limited weight that can be held up, and the small distances required between the posts. Like in any other construction there’re two forces acting upon the post and lintel system: compression and tension. The two posts are under compression from the weight of the lintel above. The underside of the lintel is under tension.
