POST AND LINTEL SYSTEM
Two upright members (post, columns, piers)
Third member (lintel, beam, girder, rafter)
The basis for the evolution of all openings
To support the weight of the structure located above the openings
LINTELFunction to bear the loads that rest on it (and its own load) without deforming or breaking to support the masonry above a window or door opening.
Failure material too weak or lintel too long
In non-classical architecture for ornamental purposes, no structural function
LINTEL
Made of wood, stone, steel or reinforced or pre-tensioned concrete
Stone lintels must be short, weak in bending
Materials strong in bending, bigger span, greater openings
Mansory lintels are inefficient cohesiveness of mortar
Description of post
• The job of the post is to support the lintel and its loads without crushing or buckling.
• Masonry post, including those of brick, may be highly efficient, since the loads compress the joints and add to their cohesiveness.
Load
Disadvantages of post and lintel system→ 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.
→ The tension induced by deformation of self-weight and the load above between the posts.
