The potters among your audience might point out that wood can burn at 1300 centigrade, somewhat beyond the "above 600 Celsius" you mentioned. this is in a kiln, but of course the kiln will only get as hot as the fire in the fire box. also the Cardington fire experiment showed that office furniture, mainly wood, can get to 1100 centigrade within about 15 minutes.

Can you do me and every other person with a working brain a favor plainly difficult? Can you please do a video on the collapse of the twin towers. You don't have to go into the whole terrorism aspect of it. Just cover the plane crash and the jet fuel melting the steel columns. Because there's so many geniuses out here that leave comments like jet fuel can't melt steel. Or that think our government had something to do with it for some odd reason. I pointed out before the open air burn temperatures of jet fuel which is way above the melting point of steel but it seems like when they're being faced with facts they just double down on their insane conspiracies.

The building lasted about 50 years. When you consider the Champlain Towers South only lasted 40 years and did not have a fire, the Wilton Paes de Almeida Building lasted a long time considering the lack of maintenance. Removing the lift, but not blocking the shaft is a chimney for any fire and the result could only be catastrophic if there is no fire suppression in the building and people prepared to use it. It is a miracle that the death toll was so low when you consider the disasters other towers have been.

[@No0dz]

Some comments from a civil engineer living for a few years in São Paulo: 1 - For several reasons, most buildings in Brazil are made of reinforced concrete, and especially for buildings delivered in the 60s and 70s, were calculated with VERY generous margins of safety. This means a lot of older, derelict structures are able to withstand a lot of neglect before failing. The lack of seismic activity and significant wind loads also enable a very lax attitude toward structure maintenance. This building, by being both old and with a more daring structure, was a disaster waiting to happen 2 - Housing is such a serious issue in São Paulo that you can assume any building that remains empty needs constant security to remain free of squatters. There are no good guys in this issue, and no solution in sight either.

However, twisting motion and fire, while possibly causing floor collapse, are not sufficient to turn the center columns of steel and concrete into dust as the building collapsed straight down at the speed of gravity leaving nothing but a pulverized pile of debris. The building was obviously imploded. So the big question is, "who gains from this disaster?"

[@thepagan5432]

Having worked over Sao Paulo and renting an apartment, it was obvious that some buildings were well cared for and others were left to slowly decay. Some buildings in the centre of the city were so close to the neighbouring building that a person could not pass between them, making maintenance virtually impossible. This fire and collapse is a very sad occurrence in a country where shanty towns and the poor have to find accommodation which may well nresult in injury and death.

@@ChrisFord-wh1gl Bridges and other steel structures do it all the time when there is a fire. If it’s unprotected, it’s going to come down sooner or later if there is a bad fire. Steel is only good to about 400-500 degrees F. Above that bad things start to happen, esp. if it’s a lower quality steel. If you have ever done metalwork you will know ow what I mean. Once it starts to glow it bends like cheap plastic. There is only so much safety factor there, and to make matters worse thermal expansion exacerbates this since the structure doesn’t expand evenly. High rise fires with huge internal drafts and lots of fuel can easily exceed 1000 degrees F. I don’t care what the models say, by that point the building is made out of play-doh if they have not insulated the steel and taken proper precautions.

[@mysock351C]

We had a fire here in Hobart (Tasmania), where a 3 story department store caught fire (electrical fault due to early 20th century wiring that had not been disconnected during multiple later renovations). In the aftermath, a steel I-beam (approximately 40cm deep with top and bottom faces of ab15cm) that was one of the main structural element supporting the top floor, was still connected at either end to the ‘pockets’, but sagged along its entire length so much that it was snaking along the floor from about 5m from each end. It was amazing to see the stretching had done very little to alter the overall shape of the I-beam, and that once it had sagged to the ground, it had continued to expand, so it was zigzagged across the floor. Luckily there were no fatalities, and firefighters had managed to rescue several people that had been stuck in the elevator at the time of the fire starting.

Reinforced concrete will fail in a fire if the fire is severe enough. The concrete starts to develop cracks when the steel reinforcement deforms due to the temperature reaching a critical point. The concrete rebar cover provides a passive form of fire resistance, for high rise buildings an 180 minute fire rating is common. It can take many hours before the structure finally fails. In 2008 a tower of the Delft University collapsed after being subjected to a massive fire, it collapsed after about 8 hours, it had an in-situ concrete frame with rather slender columns (the stories where double height which negative affected the buckling strength). Maybe interesting case for a future video.

He said that they did not have any official record keeping of tenants in the building so there is no way to know if that number is correct or not. When the WTC collapsed, countless people were never accounted for. He said this building burned for about an hour before it collapsed. And when buildings like this collapse, it is essentially like throwing a human body in a blender. If any people were inside that were not able to get out, and their bodies were burning for an hour, and then went through the collapse, there very well could have been more people unaccounted for that were never found. And I don't know how they handled the cleanup, but with the WTC site they scooped up every pile and combed through it a couple of times for any sign of human remains (as well as other things) at an off site location. I doubt they went through such efforts with this. The deaths were low I agree, but the point being is he said "at least seven people died in the collapse, however numbers were not certain".

These buildings are designed to collapse straight down - given most highrise occurs in dense clusters , it would risk a domino effect if they did otherwise. My father worked in structural engineering and mentioned that the then newest and tallest office building in our town could be brought down by removing one particular beam. He didn't reveal which it was, or what mechanism was required to initiate. The building is now over 30 years old, and in the shade of newer, taller structures.

The beams had shifted and contorted and they thought that weight on them would bring it down

[@plunder1956]

A dubious construction method was used in many Post-Tension Reinforced Concrete structures in Brazil in the 50s-70s. The post-tension wires are stretched using clutches - then grouted in place. After that another layer is added above them and so on. This makes any normal method of explosive demolition impassible. Cutting the reinforcing wires would instantly release all that energy. Sending long high strength steel wires shooting into the air - WITH THE CONCRETE they are holding back. They are like a stack of live bombs. They must be carefully taken apart, layer by layer 🤐

[@EdgyNumber1]

That's why steel beams are coated with a volcano like slurry similar to that for making shell moulds in manufacturing. It significantly reduces heat transfer and can protect the beams from fire for much longer. Its not infallible though. It is brittle stuff and can withstand an impact to the building from, say, an airliner. In this case it can shatter off and leave the steel exposed.

[@rawveganterra]

If a heavy object hits the coated steel, that slurry will crack off? Like chocolate shell on ice cream? Does heat move slowly or fast through steel, I would guess it heats up fast? Would the whole steel structure of the building, from top to bottom, entirely become hot, like a spiral oven top burner, weakening the entire building? Or, would only sections of the steel become hot and weakened while other sections stayed cool? I guess it depends on the duration of the fire.

[@krashd]

Actually fire-proof coating can withstand impacts, it just deterorates when doing it's job meaning an inferno or a prolonged fire will burn it off. That is why WTC 1, 2 and 7 failed, the first two contained four-storey tall furnaces and the last one was left to burn for 8 hours.

[@Caffeine_Addict_2020]

@@rawveganterra So - only one, or maybe a handful of sections need to fail to bring the whole tower down, because they're all balanced on top of one another. So it's less important that the entire structure have heat spread all over, as one section having concentrated enough heat that the structure weakens to the point that it can no longer hold up the rest of the structure, and everything falls down all at once In addition to what others have said about bending and warping - there's this concept of material science called "annealing". Steel is not just one element, it's many, with different elements such as carbon deposited in specific concentrations to make it stronger, ie. carbon is highest around the outside of the steel. But when you keep the steel at a specific temperature for a while, the carbon will move around to places it isn't supposed to go, turning the steel into just iron and carbon separately, which is significantly weaker

[@rafaelHgrassi]

The problem about the people inside the building is way more complicated. In Brazil you can occupy land and buildings that are abandoned (even cars). After five years taking care of it and paying taxes it can be yours. This is used primarily to fix property documentation problems when they are too complicated and also to repurpose abandoned places. This was extended by law to any building (government and others), because there is more empty places in the city than homeless and people living in poor conditions. Due to this, it is always difficult to remove squatters and at the time, public opinion was sided with this movement (with several places). So city hall was trying to remove than legally, with the argument related to safety and minimum conditions, but movement was doing high demands. After this tragedy, things change and public opinion also. Most of people understood that safety concerns are in fact valid arguments against this type of situation, not just government trying to get rid of people.

That heaps of trash and dirt everywhere is a direct reflection of inhabitant minds. They could keep their place clean, they could team up to remove the trash out of the building.

But squatting attracts a kind of disruptive people not interested in anything positive.

Brazilian regulations about required fire resistance of structures weren't as good as they are now when the building was designed.
