Introduction
With
few
exceptions,structures
must
be
stable
under
all
conditions
of
load
;
thatis,they
must
be
able
to
support
applied
loads(their
own
weight,anticipated
liveloads,wind,and
so
forth)without
changing
shape,undergoing
large
displacements,or
collapsing.Since
structures
that
are
stable
do
not
move
perceptibly
when
loaded,their
analysis-the
determination
of
both
internal
and
external
forces(reactions)-is
based
in
large
part
on
the
principles
and
techniques
contained
in
the
branch
of
engineering
mechanics
called
statics.The
subject
of
statics,which
you
have
studied
previously,covers
force
systems
acting
on
rigid
bodies
at
rest(the
most
common
case)ormoving
at
constant
velocity;
that
is,in
either
case
the
acceleration
of
the
body
is
zero.
Although
the
structures
we
will
study
in
this
book
are
not
absolutely
rigid
because
they
undergo
small
elastic
deformations
when
loaded,in
most
situations
the
deflections
are
so
small
that
we
can(1)treat
the
structure
or
its
components
as
rigidbodies
and(2)base
the
analysis
on
the
initial
dimensions
of
the
structure.
We
begin
this
chapter
with
a
brief
review
of
statics.In
this
review
we
considerthe
characteristics
of
forces,discuss
the
equations
of
static
equilibrium
for
two-dimensional(planar)structures,and
use
the
equations
of
static
equilibrium
to
determine
the
reactions
and
internal
forces
in
a
variety
of
simple
determinate
structuressuch
as
beams,trusses,and
simple
frames.
We
conclude
this
chapter
with
a
discussion
of
determinacy
and
stability.By
determinacy,we
mean
procedures
to
establish
if
the
equations
of
statics
alone
are
sufficient
to
permit
a
complete
analysis
of
a
structure.If
the
structure
cannot
be
analyzedby
the
equations
of
statics,the
structure
is
termed
indeterminate.To
analyze
an
indeterminate
structure,we
must
supply
additional
equations
by
considering
the
geometryof
the
deflected
shape.Indeterminate
structures
will
be
discussed
in
later
chapters.
