BEAM

A structural member, usually
horizontal,

that
carries a load that is
applied

transverse
to its length.

COLUMN


An upright structural member
acting

primarily
in compression.

CURTAIN WALL

An exterior building wall that is supported
entirely by the frame of the building, rather
than being self
-
supporting or load bearing.


DEAD LOAD

The weight of the building or building
components.


DEFLECTION

The distance a beam or structure
deforms

under
loading, typically due to bending in
a

beam
.

FREE

BODY DIAGRAM

A diagram used to isolate a body from
its

environment
, showing all
external

constraints
and forces acting upon it
and

all
geometric measurements necessary
to

model
the body.

GIRDER

A horizontal beam that supports
other

beams
; a very large beam, especially
one

that
is built up from other sections.

LIVE LOAD

The weight of movable objects such as
people, furnishings, machines, vehicles,
and goods in or on a building.


LOAD BEARING WALL

A structural wall that carries loads other
than its own weight.


NON
-
LOAD BEARING WALL


A wall that does not carry vertical load
other than its own weight.


REINFORCED CONCRETE

Concrete
into which steel reinforcing bars
have been embedded to impart tensile
strength to the construction.


SAFETY FACTOR

A factor intended to compensate for
uncertainties in design and analysis by
reducing the theoretical strength of a
member for use in design.

SEISMIC LOAD

A
load on a structure caused by movement
of the Earth relative to the structure during
an earthquake.


SPAN

The distance between supports for a
beam, girder, truss, or other horizontal
structural member; to carry a load
between supports.

STRENGTH

The capacity of a structure to resist the
effects of loads.

TRIBUTARY AREA

The
area of floor or roof representing the
surface area from which an applied
uniform load is assumed to transfer to a
supporting structural member.


TRIBUTARY WIDTH

The
width of floor or roof along the length
of a beam, measured perpendicular to the
beam, representing the portion of surface
from which an applied uniform load is
assumed to transfer to that beam.


TRUSS

An
assembly of structural members joined
to form a rigid framework, usually
connected to form triangles
.


WIND LOAD

Pressure
from the wind that can cause
lateral loads as well as uplift on the roof or
downward pressure.
