STANDOFF DISTANCES
STANDOFF DISTANCES
 For some wall
types…will require
window and door
construction that is
significantly heavier and
more expensive than
windows and doors
designed at the standoff
distances in previous
versions.
 Tradeoffs will have to be
analyzed when:

STANDARD 1: STANDOFF DISTANCES
CONVENTIONAL CONSTRUCTION
PARAMETERS
 Figures B-1 and B-2 have many Qualifications
(PAGE 1/2)
 Building structure must meet Conventional Construction Parameters to use
the conventional construction standoff distances provided in these tables
 If the building structure does not meet Conventional Construction
Parameters OR if there is not adequate standoff distance, then the structure
needs specific analysis or hardening for blast effects at the available standoff
distance
 Windows and doors must be designed for the applicable standoff distance
 Windows and doors need to be properly anchored to the supporting
structure
 The structures around the window and door openings need to be designed
for the increased applied loads due to larger tributary areas to the adjacent
supporting elements

THE PROBLEM
(PAGE 2/2)
How are we supposed to determine what is the
 CCP are fairly well
best Standoff Distance for our building?
defined for exterior
walls unless you have
very tall walls
How can we quickly get the window and door
supplier to give us a quote?
 Roof systems are
very limited. Most
commonly used roof
systems will need to
be designed for blast
pressure.
What glazing size and type will work best for our
project?

addressed in UFC 4-020-01…
 UFC 4-010-01, B-1.1.1 Conventional Construction Standoff Distance
 Those tradeoffs will generally need to be analyzed when standoff
distances are less than 82 feet (25 meters) for Explosive Weight I
and 33 feet (10 meters ) for Explosive Weight II. There are tools in
UFC 4-020-01 that can assist in evaluating those tradeoffs.
