...people and property in the fuure," said Arden L.
Bement Jr., director of Gaithersburg, Md.-based NIST in March
6, 2002, congressional testimony regarding funding for the
research. "This broader program would address critically
and urgently needed improvements to national building and
fire standards, codes and practices."
Schulte thinks that is hogwash,
claiming NISTgot funding based on promises it cannot keep.
"Prior to initiating the investigation, it should have
been determined whether or not we expect buildings to withstand
terrorist attacks," he says. "If the answer is no,
then there is absolutely no point" to the study, he adds.
"Since Sept. 11, 2001, over
110,000 Americans have died on our nations highways,"
Schulte says. "Why are we spending tax dollars on an
investigation of the collapse of the World Trade Center, rather
than on trying to reduce highway fatalities?"
Structural engineers also voice
concerns about the study. "NIST needs to be very careful
about defining a rational design hazard for office buildings,
which is the occupancy under study," says John D. Hooper,
a principal of Magnusson Klemencic Associates, Seattle, and
chairman of ICCs structural subcommittee.

Igniting an office filled with
jet fuel and measuring results is of no relevance to codes
because the scenario is not consistent with the fire hazard
associated with that occupancy. "They are blurring the
line so people will think the codes will address hazards [associated
with] 9/11," says Hooper.
Lawrence G. Griffis, president
of the structures division in the Austin, Texas, office of
Walter P. Moore and Associates Inc., sums it up: "The
buildings in the World Trade Center collapsed because of a
malicious terrorist attack. Everything that followed was a
result of that attack.
"Jon Magnusson said
it very well" on Peter Jennings national ABC television
news broadcast on 9/11, says Griffis. "The question is
not why those buildings fell down but why they stood up [for
so long]. If you want to stop those types of building collapses,
lets not indict the design process, lets stop
airplanes from flying into buildings."

Frames Should Be Designed
to Defined Hazard

In a spring 2003
viewpoint, Life Safety in High-Rise Buildings After
9/11, published by the Society of Fire Protection Engineers
in Fire Protection Engineering,
Construction Technology Laboratories W. Gene Corley
concludes that for the life safety of those who may
be trapped in the building and of those who must fight these
fires, the design objective should be that no collapse occurs
with a burnout. Also, the burnout considered should be related
to the amount of fuel in the building if fuel exceeds the
amount that would produce a standard ASTM E119
fire.
Walter P. Moores Lawrence
G. Griffis agrees with Corleys intent to design a frame
to avoid burnout, but with qualifications. He says the design
hazard selected should be based on the anticipated use of
the building and not a terrorist event or other malicious
act unless that event is stated as the design basis.
Griffis is more troubled by other
points in Corleys article, such as the experience
after the 9/11 attack...proved a building can collapse as
a result of fire.
This gives the impression buildings
are being designed with insufficient fire protection, says
Griffis. In the case of the WTC towers, is it not obvious
that the fuel furnished to produce these fires was far in
excess of the design hazard? he asks. Any building
will collapse from fire if the fuel source is large enough,
he says, and any fire protection system can be overcome if
the fuel input exceeds that for which it was designed.
Griffis also takes issue with Corleys
statement, Of more importance to the fire protection
community, however, were the collapses of buildings WTC 5
and 7. These two buildings collapsed during burnout from fire
even though there was no evidence found that the collapsed
areas had been seriously damaged by impact of debris.
Corley agrees that it is imperative
to define the hazard, which should not be a missile attack.
But if you change office space to a law library,
he says, you should check to see if the structure can
carry the added gravity and added fire load.
Corley also says that, barring
an unusually high fire load, it is probable there would be
no additional cost to design a building to avoid collapse
before burnout.

Chasers and False Statements

Richard C. Schulte,
gadfly to some and hero to others, becomes borderline apoplectic
over the World Trade Center investigation by the National
Institute of Standards and Technology. It appears the
only thing NIST has determined from a fire-safety standpoint
so far is that womens shoes make it difficult to evacuate
a high-rise building quickly, he says.
NIST is not his only target. Soon
after 9/11, the Evanston, Ill.-based code consultant became
a fire protection engineer with a cause. He spends a great
deal of time debunking what he considers false statements,
exposing agendas, slamming sacred cows and going against the
grain.
Schulte is a 1976 graduate of the
Illinois Institute of Technology, with a degree in fire protection
engineering and a minor in structural engineering. He hung
out his shingle in 1988 and has never been a member of the
Society of Fire Protection Engineers because they do not represent
his interests. They are like a union or guild, looking
for work and ways to make money, he says.
Schulte figures his outspoken ways
are damaging his career. I dont need a fancy car
or a big house, he says. (He drives a 1995 Toyota Tercel
that has 224,000 miles on it and lives and works in a three-bedroom
townhouse in Evanston, Ill.)
Schulte advises on the best
ways to comply with fire codes for the least amount of money
and is affiliated with the National Fire Protection Association
and the International Code Council. His regular soapbox is
an unpaid column in Plumbing Engineer.
The American Institute of Steel
Construction is decidedly pro-Schulte. Concerned about post-9/11
backlash against steel frames, AISC distributes a 40-page
reprint of Schultes Plumbing Engineer articles from
August 2002-2003.
Schulte says he is able to write
for the magazine because he is not offending...
