POST +AND+LINTEL

= POST AND LINTEL =

====**Post and lintel** is a simple form of construction where a horizontal member (the **lintel**—or **header**) is supported by two vertical posts at either end. This form is commonly used to support the weight of the structure located above the openings in a bearing wall created by windows and doors.====

** Disadvantages **
====The biggest disadvantage to a post and lintel construction is the limited weight that can be held up, and the small distances required between the posts. Roman developments of the arch allowed for much larger structures to be constructed.==== ====There are two main force vectors acting upon the post and lintel system: weight carrying compression at the joint between lintel and post, and tension induced by deformation of self-weight and the load above between the posts. The two posts are under compression from the weight of the lintel (or beam) above. The lintel will deform concave up because the underside is under tension and the topside is under compression.====
