Ausie Engineers say Austrailian Buildings vulnerable to collapse, page 1

University of Melbourne engineers have found Australia's tall buildings are likely to collapse following even a moderate bomb blast or collision with a light aircraft.

Associate Professor Pryian Mendis and PhD candidate Tuan Ngo assessed Australia's tall buildings and constructed a computer model of a standard 52-storey Australian-designed building. Using sophisticated computer software, they then investigated what would happen to the structure under extreme loading from bomb blasts or collision from a light aircraft.

They have presented their research at a number of national and international conferences this year. They will present a similar paper at the International Association for Bridge and Structural Engineering (IABSE) symposium in Melbourne this week.

"Under the extreme loading experienced during such events most Australian tall buildings would probably suffer progressive collapse, which occurs when a section of the building fails to support the load above and triggers a cascade of failures leading to the collapse of most or all of the building. The Murrah building in Oklahoma, which collapsed in 1995 after a bomb went off, and the World Trade Centre suffered this fate," says Mendis.

Hmm, I wonder if these guys have heard of Steven Jones, the BYU physicist?

How did that part go again? Oh, yeah. . .

They have presented their research at a number of national and international conferences this year. They will present a similar paper at the International Association for Bridge and Structural Engineering (IABSE) symposium in Melbourne this week.

No probably not. They apparently are to busy getting their paper peer reviewed by real scientists and engineers.

Howard, you make it so easy for us. I don't know where to start.

More "pancake theorists" selling bad science. A hypothesis based on one single incident which has never occurred before, and has not nor cannot be reproduced since. If two guys in Melbourne say the Earth is flat yet can't produce any results of real-world experiment or real-world observation to support their hypothesis, then I'm sorry, the rest of us will just keep believing that the Earth is round.

Let's see what they have to say...

Australia's tall buildings, and many others around the world, are designed around a central core that contains things such as the lifts and emergency stairs. This core is designed to take most, if not all, of the loading that comes from forces such as wind or earthquakes. The external frame is designed to take vertical loading in the form of weight from the structure above and human and materials on each level only.

Their hypothesis, by their own admission, is based on the observation of the WTC towers. NEWSFLASH guys: the WTC towers were not designed at all in the way you describe! The WTC cores were designed to take 50-60% of the vertical load. Back to the drawing board, eh fellas?

"This way, if one or more support columns and beams are knocked out, progressive collapse is prevented as the load from above is distributed laterally and onto other columns and beams," says Mendis.

Did these two just get out of bed or what? If they actually do some reading they might discover that the WTC towers were designed specifically with lateral load distribution between the core and the perimeter, and between columns in each.

But wait, it gets better...

"It was estimated that 80 per cent of the deaths in the Oklahoma bombing were due to the progressive collapse of the building rather than the blast itself."

Wow, these guys really need to do some more homework. Here is what the man who was called in by the US government to investigate the OKC bombing, USAF ordinance expert Bigadier General Benton K. Partin, concluded about the building damage and "collapse":

www.okcbombing.org...

And guess what? The Murrah building was still standing after half the building was blown away. Because the bombs that were still in the building failed to explode. And they had to call in a demolition crew to destroy the building. Ironic, eh?


But what's most amusing about the few lemmings who are coming out with this all-new "pancake collapse" theory which has never been reproduced before or since that one day in Sept 2001, is that their hypothesis is never presented to the people who deal not in bogus science, but rather in real-world application of real science in building collapse, i.e. demolition experts. If this 'Earth is flat' hypothesis were true, it should be revolutionizing the demolition industry worldwide. But whaddyaknow, demolition corporations are still imploding buildings the good old fashioned way, destroying all the columns and supports in a building. I don't see any of them consulting with these two guys in Melbourne about how buildings can be imploded by knocking out a column or two at the top 8% of the building.

Perhaps associate professor Mr. Mendis and his friend Mr. Ngo the "PhD candidate" should give a real professor a call. I'm sure Professor Jones can give them a lesson or two in basic physics for free; he seems like a nice enough bloke. And perhaps they can explain to him how their computer game predicts pools of molten metal in the basements of these imploding buildings. That would be a good one.

Is their paper published online so we can take a look at what other gaping flaws it contains?

Rialto Towers is the tallest reinforced concrete structure in the Southern Hemisphere and is well known for its unique design and glass facade.

www.rialto.com.au...

It was built in the mid-1980's and is the third highest reinforced concrete building in the World.

www.australianexplorer.com...

Wasn't that the official reason why the WTC caught fire and collapsed... atleast orginally?
The steel wasn't re-enforced, therefor the fire destroyed the steel, one floor gave and the others followed?

So why would the Rialto fall anything like the WTC?
If we're talking about bombs, well that's not how the WTC fell now is it?? So far there's no likening to the WTC.

After 9/11 there was actually a fair bit of anaylsis done on the Rialto and why it was stronger than the WTC. Obviously people were asking the question of how safe it is and the fact it is re-enforced was the reason why it's stronger.

Might be worth starting a database of info about the Rialto just incase they dare try to bring it down and all the facts posthumously start changing. Thou i still think it will follow the London script and just be a bomb on a train, probably in Sydney since Melbourne wouldn't want to tarnish it's reputation with the Commonwealth Games in 2006. That would be the easiest thing for them to pull off, nowhere near the amount of security and cameras that London had, plus making it Sydney will mean Melbourne can put on a security show to impress the visiting nations and boost the security budget. It doesn't have to be a massive attack for Australias government to take advantage of it, they don't need to do much.

Howard has already got his "Christmas wish" and got all his laws through before Christmas so they're getting ready for something - infact they keep telling us that something is going to happen one day.

I hope it's the latter, because in the process they will only show the weaknesses in their case even clearer.

But hey, did you mean this thread to be a credibility attack on Prof. Jones, or about your two goons from Down Under, Pryian and Ngo? tsk, tsk...If you wear transparent tactics, Howard, everyone can see what color panties you have on.

WCIP, I am amazed at your attempts to put words into other mouths.

“Their hypothesis, by their own admission, is based on the observation of the WTC towers. “ Where, pray tell, in that article do they admit this?

I found another version of the article. Nope, they don’t “admit” that their hypothesis is based on the WTC collapse at all.

The finding comes from a study by Associate Professor Pryian Mendis and PhD candidate, Mr Tuan Ngo, who constructed a computer model of a standard 52-storey Australian-designed building.

Or are you stating that the design for the WTC building is standard for Australia.

What the modeled is a STANDARD box frame building with a rigid core. Nowhere in that article are they making any claims regarding the WTC towers. YOU are the one jumping to the conclusion that they are.

So? No where in the Australian’s article do they insist that the building has to collapse totally, just that a collapse either in part or in total, can occur.

Yeah, he had to edit his on-line version to take out the part where he claimed that is was going to be published by a peer reviewed journal when in fact it has only been accepted by the Marxists rag so far.

I bet his colleagues were giving hem a hard time for the quality of his “peer” review.

If Jones was patient, then why did he release his paper on-line before it was peer reviewed?

The sad truth is, Jones, like the Idaho weatherman and Pierre Sallinger, has pretty much thrown his career down the tubes based on internet myths.

From your linked article:

www.unimelb.edu.au...
Associate Professor Mendis says that under the extreme loadings experienced from a bomb blast or light aircraft collision most Australian tall buildings would probably suffer progressive collapse.

"This occurs when a section of the building fails to support the load above and triggers a cascade of failures leading to the collapse of most or all of the building," he says.

"The Murrah Building in Oklahoma collapsed in 1995 after a bomb blast and the World Trade Centre suffered this fate."

Seems to me that your two heros above are referring quite clearly to the WTC collapses and the Murrah building as examples of their hypothesis in action. In fact, those are the only examples they mention. And you know why? Because no other buildings have gone into progressive collapse before without the aid of explosives. Terms like "progressive collapse" and "pancake collapse" have only appeared in structural engineering in relation to tall buildings since 9-11, in an attempt to explain why those buildings collapsed. Imagine it, a complete Copernicus-like revolution in the structural engineering world, with billions of dollars being spent on finding ways to prevent buildings from exploding themselves down to the ground when they catch on fire, all based on just three buildings that all collapsed in one day, never before, and never since. Newsflash guys: The buildings WERE collapsed using explosives.

Hilarious...

Nowhere in that article are they making any claims regarding the WTC towers. YOU are the one jumping to the conclusion that they are. Where is it written in that article that they are talking about the WTC?????

Howard, I don't think I've ever seen you backtrack this fast in all the time I've been at ATS. You say I am jumping to conclusions here, eh? That you innocently posted this as a bit of random news in relation to structural engineering, right? Well let me ask you this, dear Howard. If the article and the hypothesis has absolutely nothing to do with the collapses of the WTC buildings, then WHY THE HELL DID YOU POST IT IN THE 9-11 CONSPIRACIES FORUM?! Why didn't you post it in ATSNN, or the Science forum?

Why should they read the words of a conspiracy nut?

Why not read what a structural engineer has to say?

You're calling USAF Brigadier General Partin a "conspiracy nut"? I'm not even going to dignify that with a response. Google for his name and his biography and tell me again that he's a conspiracy nut. Btw, your structural engineer wouldn't know diddly-squat about ordinance. He would try to rationalize away any OKC destruction anomalies using structural engineering reasoning. I don't envy his task, lol.

No where in the Australian’s article do they insist that the building has to collapse totally, just that a collapse either in part or in total, can occur.

Once again, from your link:

"This occurs when a section of the building fails to support the load above and triggers a cascade of failures leading to the collapse of most or all of the building," [Mendis] says.

You, I, and everybody else here are well aware that you posted it to say, "Look. Guys with degrees say that tall buildings can collapse completely from damage or fire. These guys support the WTC pancake theory. Nyah nyah-nyah nyah-nyaaaah nyaaah."

Truth 1, Roark 0

A hypothesis is formed in response to observed phenomena in the real world, and is an attempt to explain those phenomena. The hypothesis is further tested by experimentation, and confirmed through reproduction of expected results. Have you forgotten grade 7 science class already? The "scientific method"? Ring any bells?

Please explain for us what observed phenomenon, if not the two examples they specifically and solely referred to, their progressive collapse hypothesis is based on. Then please explain for us what, if any, relevance it has to 9-11 and the collapses of WTC1, 2, & 7.

GLOBALISM: THE PROGRAM by General Benton K. Partin. Wow! Where do I start? You want to know the opinion of a bomb expert who built many of our most sophisticated missile systems? General Partin is your man. He has received countless awards in his 31 years in the Air Force and possesses credentials eight pages long. He says TWA flight 800 was taken out by two ground-to-air missiles; the Branch Davidians at Waco had explosives used on them; the bomb in the Ryder truck in the Oklahoma City bombing could not possibly have done all the damage it was claimed; and that is only a start! He continues on to reveal "The Program" the Illuminati is following to build a New World Order. He says these bombings are part of "The Program" and you can count on more of them increasing in intensity.

Yep, as far as I am concerned, anyone who believes in the Illuminati is a conspiracy nut.

What else does your hero, General Partin have to say?

"I would encourage everyone who loves freedom...to read and reread Masters of Seduction..." --Brigadier General Benton K. Partin (USAF, Ret.)

Yep, He’s sounds like a right wing kook to me.

If you read the article, they are specifically looking at the vulnerability of common building designs in Australia to collapse.

The only hypothesis that they have presented is that based on computer modeling, these designs are, in fact, vulnerable.

Your assumption that their analysis is somehow based on the WTC collapse is wrong. The study of why buildings collapse is a very common one among structural engineers. Up to a few years ago, those studies were mainly based on earthquake events. After 911, many, engineers began to look at the vulnerability of their buildings to terrorist attacks.

If their analysis is flawed, then this will be determined by peer review. That is the purpose of peer review. Why doesn’t Professor Jones present his paper at an engineering symposium?

I think the fact that you so vehemently attacked the article and the two Australians is enough to warrant it being here.

Just like you “theorists” I am “connecting the dots.” Only the dots I am working with are based soundly in science, data, and engineering.

Forensic engineering is a fascinating subject. www.icivilengineer.com...
