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

Wood Metal Stone

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

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.
