@@ryankelly369 well, the Roman roads did not have to bear the weight of tons of trucks going back and forth a hundred times a day. Traffic was MUCH lighter back then.

Give this experiment a try. Mix 1 part lime with water until dissolved into a semi-thick liquid. At the same time mix 1 part waterglass with water until dissolved into a semi-thick liquid. Mix the two together and add the right amount of sand and gravel and add some water with common sense and logic and write down the additional amount of water you added. In the 1960s it is 1 bag of cement, 2 bags of sand, and 4 bags of gravel and add enough water until it is a semi-thick liquid which is semi-plastic and semi-liquid which can either be placed or poured with the use of POWERFUL CONCRETE VIBRATORS AND MOLD VIBRATORS. Roman concrete functions when the dissolved lime penetrates the atomic holes of the silica component which is present in the powdery fine volcanic ash and REACTS WITH IT. But this time the silica that the DISSOLVED LIME will react with WILL NOT HAVE ATOMIC HOLES FOUND IN THE SILICA COMPONENT OF VOLCANIC ASH CALLED POZZALANA BUT INSTEAD WILL REACT WITH THE EQUALLY DISSOLVED SILICA IN THE FORM OF DISSOLVED WATERGLASS KNOWN ALSO AS SODIUM SILICATE GLASS (which is also used as a glue in the 1950s and 1960s up to the early 1970s. This time the atoms and molecules of the dissolved lime with react with the atoms and molecules of the dissolved waterglass known also as sodium silicate glass or soda glass.
Ancient chinese dont use nails for building, instead, they like these traditional carentry's complicated structural joints, the design allows spaces and flexibility for the building to adapt the shockwave from earthquake. that makes it more durable and safer than pure resist. The philosphy of Yin and Yang, the beauty of balance. if we do not use the joint design that allow some flexibility, but use strong and simple joint structure with nails or gum, they wont last long, the stronger that is, the shockwave would cause more cracks on the building, then it will fall apart sooner then ppl expect.

Not really . Italy has just as much seismic activity . Never prevented them from buildings grand masonry structures all the way from antiquity to the modern day. Earthquakes = excuse = cope
Oh how fascinating. I'm making a cursory study of disaster resistance in architecture for my world building. It's truly amazing how this works. It makes perfect sense of course, but the fact that it exists is still a marvel of how we as people evolve our ideas over the generations. I will most certainly be using this kind of architecture where it is necessary.
This also aplies to pagodas, whre there's only ever been a couple of instances of pagodas recorded being destroyed in earthquakes through thousands of years. Pagodas use a central column that runs through it, and that the whole building hangs off for stability, while being flexible (and zero nails so the wood can flex). At the top they invented the mass dampener system thousands of years ago, a heavy weight (usually a round knob of stone or crenellated metal spire) that moves at a counter to the way the rest of the column moves. This is why East Asians have traditionally used wood rather than brick or stone (other than for bases or forts) for their buildings -earthquake, flood and typhoon-proofed, but susceptible to fire. There are hundreds of pagodas that have succumbed to the latter.
It also seems like the shape pointing towards extreme angles to maximize the number of tiles, stable curvature, additional ornaments and heavy earth materials are designed to maximize weight in order to stabilize the structure, like a counterbalance that pairs well with flexibility.
The joint loose structure indeed was spread to Japan and Korean. But the big distinguish is, the Japanese structures does not use the technics that connects the heavy roof and bottom pillars, leading the roof of Japanese structure cannot be super heavy
Many and details of the technologies of buildings from China are still alive here in Japan. Some of them were made more sophisticated in Japanese modern tall buildings. Recently, the government regulate law to use more nails, but still, we don't use many nails. Hello from Tokyo.
What if u add some super strong super stretchy material to the joints to act like ligaments for the bones? I dare say it might survive a pole shift/crustal displacement.
This looks like a good argument for massed timber construction, given the adhesives now available to construct better members. Incredibly stable stuff built for both natural and man-made disasters.
There is a lovely video with carpenters making these full size buildings with very rough old tools . Worth a look . Traditional Chinese House construction .
It looked like the top of the building used it inertia and the moving platform shifted back under the roof before excess damage was caused. What would happen if the moving platform did a shift to the side so the support beams were at an angle? It looks like if there was be a lateral movement large enough that the support beams would tip over enough to send the whole structure crashing down. Does the full documentary cover this?
That would be at least magnitude 12. It belongs to another book altogether. If earthquakes are producing magnitude 12s... it would be a lonely feeling to survive the quake.
Unfortunately, the modern Chinese home do not incorporate the earth quake proof technology and it is going to be a disaster when a major earth quake happen.
Marsilling, That is only true in the more modern and urbanized areas of China and Asia primary. It is not true of the country side, and many of the younger generation is looking toward natural and/or traditional building systems like this... All is not lost!! Just look at the folks reading this and thinking about it...!!!
Because ancient Chinese buildings need to consume a lot of land. And it's all wood structure. It is impossible to prevent fire. Japan, for example. A fire can easily destroy hundreds of houses.
Sorry Huang Qinyu, This is not true what you are stating here at all!!! I am a Timberwright with over 40 years of experience. 1. NO...they do not consume a lot of wood, not compared to modern "stick" wood architecture and the amount it consumes. Nor do they have the impact environmentally that modern steel and concrete architecture does. These acient systems of not only your country, but globally, are some of the most enduring architecture we have still in existence with the oldest documented forms over 2000 years in age, and the undocumented pushing 7000 years... 2. NO...they are not "all wood structure" alone, as they often have brick, stone, or cobb infill and they have stone plinth foundations. Part of the reason they are resistant to tectonic events. 3. NO...again...they are actually extremely fire resistance compare to many modern building materials. As to both acient and modern modalities they can also have the wood treated (as we do) that renders them even more fire resistant. Yes...fire did destroy historically many old structures of wood. This type of urban conflagration had more to do with war, arsin, and/or what is called..."fire load"...which has more to do with what is inside a structure...NOT...what it is made of. Many of these "city fires" happened in brick buildings as well, not only because of the wood in them, but also what was in the buildings as well. Most of the modern world is still made of "wood" but today we are employing building methods that used more "stick" than timber and they are less enduring and take less skill to craft, but that is changing a lot with your generation, and you are to be commended...

this only applies to timber framed buildings. and this is also true with Western style timber frame buildings too. but China has tons of traditional brick buildings, even more common than timber framed buildings. Where weight bearing walls are made of bricks, but the roof structures are timber. and they are not earthquake proof at all.
They built them like that because they didn't have the brains nor the courage to tell the roof makers to make lighter roofs. Idiots. A roof on a single pavillion weighs tons! It's ridiculous! Aaargh! It's not fascinating. It's just plain stupid.
Ancient engineering was much better than we (modern) people think. The Romans too, and other long gone civilizations.
Roman concrete dating back to the old Republic (hundreds of years pre-Christ) has withstood the test of time, while the best modern concrete is lucky to last more than 75-80 years.
Because while we are trying to cut prices as low as it could possibly go, the monuments, temples, and palaces of the ancients are built to last
