TOPICS

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, are
example of this, which are

strong
in both tension and compression
.


Have you ever thought of the skeleton

of
the building as the main factor design,

or
do you usually resolve

at
the end of the creative process?

INTRODUCTION

A

frame

system

is

one

whose

principal

structural

elements

consist

of

beams

and

columns

connected

through

rigid

nodes,

forming

resistant

frames

in

two

main

directions

of

analysis,

which

enables

the

transfer

of

bending

moments

and

axial

loads

to

columns

the limit can
be around 20 floors and
high seismic risk zones
that limit must be found
in about 10 floors.

ADVANTAGES



Greater
freedom in the
distribution of the inner
spaces of the building.


They are very flexible
structures that attract
small seismic action.


by the use of brick walls in
the frame system, the heat
transmited to the inside of
the building is less than
the other structures.

Concrete

Structures are the resul t of a

concrete and rei nforci ng steel.
In these cases the steel i s

FRAMED STRUCTURES WITH DIFFERENT
MATERIALS


Wood


WALL

Wall
framing in house
construction includes the
vertical and horizontal
members of exterior walls
and interior partitions, both
of bearing walls and non

bearing walls.

CORNERS

A
multiple

stud post made up
of at least three studs, or the
equivalent, is generally used
at exterior corners and
intersections to secure a good
tie between adjoining walls
and to provide nailing support
for the interior finish and
exterior sheathing

The structural configuration can be considered the fundamental
aspect in the entire structural design. These conclusions are
deduced from the experience gained in past seismic events,
showing that well
-
structured and detailed buildings have
satisfactory performance even without undergoing profound
analysis and calculations. buildings with frame system has
proven to be one of the most resistant to earthquakes and also
one of the most flexible spatially.
