The Towers, Fire-Induced Collapse and the Building Codes08/14/2003
Fire Engineering Magazine


In this report, issued July 17, 2003, Battalion Chief FDNY (Ret.) Arthur Scheuerman, presents a preliminary interpretation of the evidence in the analysis of the cause of the large loss of life and collapse of the World Trade Center Towers and recommendeds code changes to mitigate the chance of a recurrence in high-rise office buildings.

Scheuerman explains that the most probable cause and mechanism of collapse of the Towers is in contention. There are two main theories on why the Towers collapsed: one based on core column damage from the aircraft collision and subsequent core column failure from the heat of the fire, and the other from the effects of the fire on the steel bar joist, floor trusses. But, Scheurman contends, each theory stems from the position an analyst is in. For example, those in the building industry will share a different viewpoint than others.

Scheurman explains that the buildings' failures were in part due to fire codes that had been too far relaxed when the city of New York revised them in 1968. " The city is presently in the process of upgrading the Building Codes in the wake or the World Trade Center disaster, and this essay is my perspective, as a retired NYC Fire Chief, in furtherance of that process," writes Scheurman.

His report concludes with, " The World Trade Center's vulnerability to fire, as confirmed by the fire spread and mode of collapse, is partially the result of the building industry's competition for, real estate dominance and financial reward, affecting the building codes over the years. The Port Authority of New York, New Jersey using corporate and public bond financing and the governmental power of the two-state agency to sidestep the already weakened, city building code requirements effectively reduced the fire resistance and suppression capabilities and collapse resistance, in the Towers. The Government should disqualify itself from competing in the real estate industry and concentrate on regulating the competition between developers to assure fire safe building construction standards and the life safety of the people. The actual fire is the ultimate test of codes and construction practices and at the World Trade Center Towers, failed the test twice."

OTHO, there was extraordinary damage and fire, none of which would happen under ordinary circumstances.

1. Planes fueled for cross-country flight are forbidden in that airspace,

2, Any normal fire would be extinguished by the sprinkler system or the fire department.

3. The planes were purposely flown into the buildings banked to do damage over several floors. Normal fire damage would be limited to a single floor.

4. Normal buildings are not designed against terrorist plots.

Bingo and the planes entry and exit caused a tremendous airflow to fuel and speed up the spread of the fire, along with the jet fuel that sat huge areas on fire compared to a normal office fire with a single small source of ignition and a much slower, less oxygen fueled fire.

If you're fairly well off living in north North America , you can live like a king in the south north to South Americas. Which is why I wouldn't be able too. lol I'll be happy if I can just afford a nice house. But even people in the states from the north sell their houses, move to the south and buy equal sized houses and have lots of money left over.

The Windsor fire produced a partial collapse, some have argued that it validates the official account of the collapses of WTC Buildings 1, 2, and 7.

Because the same fire was so massive and did not produce total collapse, others have cited it as evidence disproving that account.

Steel Versus Steel-Reinforced Concrete

In fact, comparisons between the Windsor tower and the WTC Towers are limited because of the very different structures of these buildings.

The Twin Towers and Building 7 were both 100% steel-framed, with large wide-flange columns and box columns, some measuring over four feet wide and fabricated of steel up to five inches thick.

Severe fires in other skyscrapers which, like the WTC Towers, were 100% steel-framed, have not produced even partial collapses.

Yea Son of Onemale, Keep trying, the steel fully collapsed, the concrete did not, BOTTOM LINE, FIRE CAN WEAKEN A STEEL STRUCTURE ENOUGH TO COLLAPSE!

<quoted text>"The fire protection on the existing steelworks below the 17th floor had been completed at the time of fire except for the 9th and 15th floors. When the fire spread below the 17th floor, those protected perimeter columns survived, except for the unprotected columns at the 9th and 15th floors which all buckled in the multiple floor fire (see Figure 2). However, they did not cause any structural collapse. Obviously, the applied loads supported by these buckled columns had been redistributed to the remaining reinforced concrete shear walls. Nevertheless, structural fire analysis should be carried out before such a conclusion can be drawn."
"On the other hand, the reinforced concrete central core, columns, waffle slabs and transfer structures performed very well in such a severe fire. It is clear that the structural integrity and redundancy of the remaining parts of the building provided the overall stability of the building."

The Windsor Building fire demonstrates that a huge building-consuming fire, after burning for many hours, can produce the collapse of parts of the building with weak steel supports lacking fire protection.

It also shows that the collapse events that do occur are gradual and partial.

Windsor Tower Partial collapse

Time Collapse Situation
1:29 East face of the 21st floor collapsed
1:37 South middle section of several floors above the 21st floor gradually collapsed
1:50 Parts of floor slab with curtain walls collapsed
2:02 Parts of floor slab with curtain walls collapsed
2:11 Parts of floor slab with curtain walls collapsed
2:13 Floors above about 25th floor collapsed Large collapse of middle section at about 20th floor
2:17 Parts of floor slab with curtain walls collapsed
2:47 Southwest corner of 1 ~ 2 floors below about 20th floor collapsed
2:51 Southeast corner of about 18th ~ 20th floors collapsed
3:35 South middle section of about 17th ~ 20th floors collapsed Fire broke through the Upper Technical Floor
3:48 Fire flame spurted out below the Upper Technical Floor
4:17 Debris on the Upper Technical Floor fell down
7

These partial collapse events, spread over several hours, contrast with the implosion of WTC Building 7 in 7 seconds, and the total explosive collapses of each of the Twin Towers in under 17 seconds.

NOT 7 Second son of Onemale, And the tower was not HIT BY A PLANE OR A CHUNK OF THE NORTH TOWER,

YOU PROVE YOUR DISHONESTY, YESTERDAY YOU USED IT TO SHOW WHY THE TWINS COULD NOT COLLAPSE AND NOW A FEW POSTS ABOVE YOU SAY IT CAN'T BE USED TO COMPARE TO THE TWIN TOWERS,

LMFAO, retarded twoofer, you have a conclusion and try to force the evidence to fit while you contradict yourself.

Retarded son of one male, you start with a conclusion, then yesterday state that the Windsor tower proves that the WTC collapse can not be explained by fire, then you state a few posts above it can not be compared to the WTC.

How freeking dishonest can you be, evidence does not matter to you, only the conclusion that must fill that void in your life as you clean out the Slurpee machine.

"Behavior of Steel-framed Buildings in a Fire"

"All common building materials lose strength when
heated to high temperatures. Figs. 1 and 2 show the
deterioration of steel and concrete mechanical properties
with increasing temperatures. Although steel does not
melt below 1,500oC, at a temperature of around 600oC, its
yield strength declines to about one-third of its yield
strength at ambient temperature. At 800oC, its yield
strength is reduced to 11%, and at 900oC, to 6%. The
elastic modulus of steel is similarly reduced with increasing
temperatures, but at a higher rate. Due to internal
cracking and chemical changes, concrete also loses
strength and stiffness as temperature increases, as seen in
Fig. 2. Since concrete has much lower thermal conductivity
than steel, a concrete encasement is often used as a fire
protection for steel. The degradation of structural materialsí
stiffness and strength at high temperatures may, in some
incidents, cause the structure to collapse under severe fire
conditions."

Interesting how engineers the world over agree that fire is bad in steel framed buildings and can cause collapse....and no credible engineers or engineering associations agree with twoofer OPINIONS.

The primary reason tilt up construction requires glue beams instead of metal tusses is the fact that metal fails but wood glue beams don't. In one test, a large beam and a comparable metal I-beam were subjected to a prolonged fire, hot enough to cause the I-beam to lose it's strength and fail to hold it's load. The heavy timber was still able to hold the load.(Western Woods Use)

"After 20 minutes of fire exposure, the deflection rate increased rapidly until it had reached 35 1/2 inches in 29 minutes. The temperature near the steel at this time was 1422 deg F. Although the steel supported panel fell into the test chamber after 30 minutes of exposure, it is evident that its structural integrity was in doubt long before this."

"The wood beam continued to support its full design load, throughout the test, with a maximum deflections of only 2 1/4 inches at 30 minutes. The uniform deflection rate of the wood beam demonstrates the dependability of heavy timber framing under fire conditions."

"t the conclusion of the test, the wood beam was sawed through at a representative section, revealing a depth of char penetration of approximately 3/4 -inch on each side and 5/8 I-inch on the bottom.... Thus, after 30 minutes of fire exposure, during which temperatures in excess of 1500 deg. F. were recorded, 75 per cent of the original wood section remained undamaged and the beam continued to support its full design load."

Interesting... "CAN cause collapse"
That is NOT saying that it has ever happened.
And it's not specifying if it CAN be a total collapse or a partial collapse.
You're sources doesn't say what you want it too.
