A

framed

structure

in

any

material

is

one

that

is

made

stable

by

a

skeleton

that

is

able

to

stand

by

itself

as

a

rigid

structure

without

depending

on

floors

or

walls

to

resist

deformation
.





Materials

such

as

wood,

steel,

and

reinforced

concrete,

which

are

strong

in

both

tension

and

compression,

make

the

best

members

for

compression
.

Masonry

skeletons,

which

cannot

be

made

rigid

without

walls,

are

not

frames

frame construction has been the
system of choice for many years. It has also
been the subject of much research into the
optimum value engineered framing design
.
For the most part, this research has been focused on
the downward loads on the structure. More recently,
as a result of the losses associated with Atlantic
hurricanes, the capacity of the building to withstand
uplift has become an important subject.



Steel framing design offers greater
strength compared to its weight, which
facilitates safe construction of high
-
rise or
complex buildings. Because steel is
manufactured mechanically, it provides a
consistency that can not be found with
wood
-
framed buildings.


Basically, a frame house is one that's supported
by its walls. The walls, that is, do more than just
enclose the house; they also hold it up. This
contrasts with, say, post
-
and
-
beam
construction, in which most of the weight of the
building sits not on its walls but on horizontal
beams supported by vertical posts inside the
building.


The outbuilding relies solely on its walls for
support, so it's of pure frame design. Frame
construction is probably the easiest kind for the
beginner because structural members are
comparatively light and easy to join together. It
also requires only a minimum of engineering,
and its basic principles can be mastered fairly
swiftly.




The heavy timber frame, in which large posts, spaced
relatively far apart, support thick floors and roof
beams, was the commonest type of construction in
eastern Asia and northern Europe from prehistoric
times to the mid
-
19th century.



It was supplanted by the American light wood frame
(balloon frame) , composed of many small and
closely spaced members that could be handled
easily and assembled quickly by nailing instead of by
the slow joinery and dowelling of the past.


Modern heavy
-
timber and laminated
-
wood
techniques, however, provide means of building up
compound members for trusses and arches that
challenge steel construction for certain large
-
scale
projects in areas where wood is plentiful.
