Industrial
steel
structures—such
as
pipe
racks,
material
handling
systems,
transfer
structures,
and
equipment
supports—present
a
distinct
set
of
challenges
compared
to
conventional
building
design.
These
systems
are
often
governed
by
heavy
equipment
loads,
irregular
geometry,
non-building
load
combinations,
and
serviceability
or
constructability
constraints
that
demand
careful
analytical
judgment.
Unlike
repetitive
floor-framed
buildings,
industrial
structures
tend
to
be
highly
bespoke.
Each
project
requires
deliberate
decisions
around
idealization,
load
application,
boundary
conditions,
and
analysis
method
to
ensure
the
model
reflects
real
structural
behavior.
Load
Definition
and
Application
One
of
the
primary
drivers
in
industrial
steel
design
is
load
characterization.
Gravity
loading
is
frequently
dominated
by:
Concentrated
equipment
reactions
Conveyor
or
material
surcharge
loads
Pipe
contents
and
thermal
effects
Construction
and
maintenance
load
cases
These
loads
rarely
align
cleanly
with
member
grids
and
often
require
explicit
application
at
nodes
or
along
members.
Engineers
must
take
care
to
apply
loads
at
realistic
elevations
and
attachment
points
to
avoid
unintentionally
stiffening
or
softening
the
system.
Lateral
loads
may
be
generated
by
wind,
seismic,
operational
effects
(e.g.,
surge
or
braking
loads),
or
equipment-induced
horizontal
forces.
For
industrial
structures,
these
loads
are
often
not
distributed
uniformly
and
may
govern
localized
members
rather
than
the
global
system.
