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
LINTEL
Function  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 pretensioned 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
Load
•
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.
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.
