Is the simplest way of illustrating loads and support in
construction.


Consists of two upright members which hold up a third
one laid horizontally across their top surfaces.


These members are:

POST


LINTEL

A post is A long piece of
wood or other material
set upright into the
ground to serve as a
marker or support.

Is a vertical support
structure.

Posts and columns do
not have to be round.

Vs.
Column

Post

A column is a vertical support structure. Columns do not have to be round. Here are examples of columns in our community.




Here are examples of posts:

Tapered posts on this
bungalow style house

support a large overhanging
roof.

These post chimneys do not support
anything

other than their own weight, they are
capable


of supporting other weight (with a
proper foundation below).

This large post

at Grand View Hospital
in


West Rockhill supports


a water tower.

Lintel

The lintel is the way of close a
vain plain, using slab of
stone, a trunk of wood and, in
the actuality, for a metallic
girder and cement.


Function

Besides holding up the structure of a
building, the lintel can be used in a
decorative way. For example,
people used to wright on the lintels
of many houses and churches
commemorative phrases and
meaningful words.

Lintel

The weight of the piece that constitutes the lintel
downloads vertically to the floor this way the extremes
of the lintel remain firm, while the central pieces which
aren’t supported, have more danger of sinking.


The central part
of the lintel is
their weak part.

Lintel

While the space of separation between columns is
wider, the lintel will be more volatile. The height is
not involved in the stability of it.

From a structural point
of view, a lintel works
as a beam, therefore
supports the efforts of
bending that affect the
compressions from the
same section.

This very simple form
of structure, commonly
used to support
windows and doors.

There are two main forces acting upon the post and
lintel: compression and tension. The two posts are
under compression from the weight of the lintel (or
beam) above.

lintel solutions can be executed in various
materials, but gravity subjects the horizontal members
to bending stress. Wood, steel, and reinforced concrete
are efficient as beams, whereas masonry, because it
lacks tensile components, requires much greater bulk
and weight.


Appropriate Materials

Post and Lintel in Neolithic,
Ancient Greek and Ancient
Egyptian Architecture


Ancient Egyptian and Greek
architects made extensive use of
Post
-
and
-
lintel construction to
support the roofs of temples and
public places.



In Post
-
and
-
lintel construction they
would use many kinds of stone.
Stone and marble were chosen for
important monuments because they
are incombustible and can be
expected to endure




Stonehenge is a well
-
known
example of an ancient post and
lintel construction. As a result the
lintels had to be made especially
thick and wide in order to increase
the amount of mass they had to
resist.



This form of construction is still
found in homes for windows and
doors
