What are post-and-lintel constructions? It is a simple architrave, where a horizontal member is supported by two vertical posts at either end. can be found in: doorways windows and the framework of many buildings. It supports a large amount of weight Variations: crossbeams, arches and walls added for extra support or as design elements.

What are post-and-lintel constructions? Designed primarily to hold weight, such as a roof or deck, depending on the vertical posts it rests on. It can support a huge amount of weight, and is effective for reinforcing tall buildings or heavy structures. The post supports the lintel and its loads without crushing or buckling, so it refers to the vertical support.

Materials P O S T A N D L I Wood Metal Stone E Lintel materials: Brick or stone, weak in tensile strength  steel for long lintels. Masonry lintels are especially weak Post materials: strong in compression. Stone superior to wood but not to iron, steel,or reinforced concrete Masonry posts highly efficient

Advantages and Disadvantages P O S T A N D L I E l Advantages and Disadvantages Advantages: -Post-and-lintel is the simplest of structural systems. -Homes constructed with a post and lintel construction method can usually be assembled quicker that other types of construction. -This construction method is considered more energy efficient than houses constructed using alternative methods because it is easier to insulate the home. -Homes that are constructed using post and lintel methods have larger interior living spaces than houses constructed using alternative methods.

Advantages and Disadvantages P O S T A N D L I E l Advantages and Disadvantages Disadvantages: - The greatest disadvantage of post-and-lintel construction is the limited weight that can be held up, and the small distances required between the posts.

Conclusion P O S T A N D L I E l The Post-and-lintel system has been used since the prehistoric times. simplicity or by the variety of materials that can be used.
