=__//**Post and lintel. **//__=



 - It is a simple architrave where a horizontal member is supported by two vertical posts at either end.

- Commonly used to support the weight of the structure located above the openings in a bearing wall created by windows and doors.

- Lintel is a horizontal beam used in the construction of buildings.

- Lintels may be made of wood, stone, steel or reinforced or pretensioned concrete.

- Disadvantages: · The limited weight that can be held up. · The small distances required between the posts · 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 above. · The lintel will deform concave up because the underside is under tension and the topside is under compression.
