Advantages

and
Disadvantages


Actual Uses


Conclusion

There are many constructive methods
and techniques to build any space. Those
constructive systems determine and
characterize the environment which is
located and the personality and needs of
the people who will or are using that
space


In the following presentation we will be
talking about "post
-
and
-
lintel",
describing this method, it's advantages
and disadvantages as structural and
decorative elements.


Simple construction method


Upright members: posts, columns
or piers


Hold a third member horizontally:
lintel, beam, girder or rafter.


In this system acts two forces,
compression and tension.


Post and lintel construction
-
pieces must fit together exactly.


Support the lintel


Failure caused because excessive weakness or
lenght


Material must be strong in compression


Stone, Iron, Steel and Reinforced Concrete


Brick highly efficient, and monolithic stone columns.


Has to be able to support without crushing or breaking.


Bear the loads that rest on it


Failure: Material is too weak or too long


Materials


weak in bending: must be short. (Stone)


Strong in bending: Bigger openings (Steel)


Masonry Lintels are inefficient, but lintels of monolithic stone,
wood and stronger materials are employed.


Has to be able to bear without deforming or breaking.


Simplicity building time is
shorter.


The walls to fill in between
the posts are prefabricated.


Stability
.


The lintel will deform by sagging in
the middle


Limited weight that can be held up.


The small distances required
between the posts.


It’s not nearly as common as
platform construction.


The weight of each piece.

Nowadays,

most

post

and

lintel

construction

has

a

third

component,

the

wall,

which

adds

additional

support

and

hides

the

post

and

lintel

design

within

the

framework
.

It

can

still

be

seen

in

doorways

and

columns,

in

which

the

space

between

the

vertical

supports

is

open
.

The Post and Lintel offered a solution
for constructive problems in the early
days, it allowed bigger and stronger
buildings to be constructed. Thanks to
its simplicity it is still used in modern
architecture and the construction
systems developed form it, helped us
shape the world we live in.
