The structural analysis of this joint is simply beautiful. The internal behavior of bending moments and shear is perplexing since the system is multi point stacking. The bracket system itself allows restricted degrees of freedom for sliding. Lateral forces are dissipated with the heavyweight of the structure. This is the first time I see the bracket style. :O!
And the brackets are so aesthetic as well! Edit: like many things in their culture, japanese architecture directly 'borrow' from china but they dont mention that explicitly anywhere tho. If you know then you'd know
Nice educational video! One thing I have to correct you that China has 4 wooden structures made in Tang Dynasty left. All of them are in my hometown-Shanxi province. Welcome people from all over the world come to visit. It will be a mind-blowing experience for you.
Thank you for this video. I have looked for a good explanation of this classical chinese console system and now i finally found such a good one. It will help me for a presentation of classical chinese architecture in my university.
The Japanese architecture assembly from China during the Tang Dynasty/ Kyoto is a city that duplicates China. It is also tea and art, and many elements that the Japanese learn from this land.
Thank you for teaching. I've been looking a deeper explanation of what's been designed into these for a while, and found lots and lots of history (still great) and oddly, zero diagrams. Thank you for saving my sanity. I'd like to learn more, things like; are these parts cut to clasp together tightly, or are they fitted for flex? Great content
@@harrymu148 not true - 營造法 YingZaoFa is a classic Chinese architecture work. There are also lots of other diagrams demonstrating how Dougong and Sunmao works, but it needs to become more recognized
NOW I SEE WHY CHINESE MOSTLY USED WOOD FOR THEIR STRUCTURES . They wanted these brachets to withstand earthquakes and they werent meant to be createdby bricks. To built earthquake proof brick buildings they had to figure out a new way. Here in Sri Lanka we always used granite and bricks .we have the tallest stupas (original pagodas) made out of bricks thousands of years old still standing ,because they have unique earthquake proof construction methodes . And the monastries built mostly by granite are still standing also milleniums old.
Andre K. No this is not the same style as what they use for forbidden city. This is a Song Dynasty style used in Foguang masonry temple at Wutai Mountain, Shanxi Province in China
great lecture Katie! had you considered to address the the particular differences between Chinese, Japanese and Korean Architectural Elements, I have been at this places and almost looks the same, but paying attention you may notice the difference!
Both japanese and korean architecture were learned from China, and adapted to the environmental specificities of those areas. So for instance japanese architecture uses softer wood that’s available in their environment compared to China, which as an economic power for centuries had access to more exotic, high-quality hardwoods from indigenous provinces and S Asia. Further, since japanese style architecture was copied from the Tang dynasty in China, the building aesthetics are simpler than ie. Ming/Qing era architecture in China. Also keep in mind that both japan and korea were tribute states of China for centuries, so their architecture styles were often regulated to be a certain style so as not to clash with/exceed the sophistication of the Chinese imperial palaces (and concurrently, japan and korea had less human capital/resources and wealth than China to dedicate to the R&D necessary to build such grand structures) You can see this in korean architecture that mimics the Forbidden Palace, but is not as grand or big. Hope this helps!
I am a wood worker. The 10 x 28 foot covered patio I built on the rear of my home has no screws, except to attach to my house. Could you please email me for a project I think would fascinate you and me? I want a house built without nails or screws, made entirely of wood. These Chinese wooden frames are amazing, but the design seems to fail if made with walls, that is why they didn't have them. I believe I have come up with a solution and would like to talk it over with you.
That is a great idea to build a house with tradition skill. However, I have some concerns about safety issue. I worked for Huntington Library. They had a Japanese style bridge built by an Japanese Artisan around 1910 without any nail. It collapse couple years later. So they put the bridge back with hidden nail. I don't know which state you live in, but in California where I stay, with the earthquake issue, we have to follow the building code to design the project. You can still make it look like traditional woodwork but use some hidden fastener behind . Or, you can use the steel structure as the framing but wrap it with wood as the skin. Our Huntington Chinese Garden is using this skill to present the Suzhou style house.Hope this help with your project.Remember, safety first!
I live in NY, and I highly doubt they'd let me build more than a gazebo without nails here, but am looking at land in KY, and depending on where I end up, there is a chance this can happen.. Considering how well all of the wooden structures and their extremely heavy clay roofs hold up to all of the earthquakes near the Forbidden City, you would think there could be a way to get an exception to their rules.. Since I am living near a major fault line(that has never caused an earthquake as far as anyone knows), I may or may not be able to build it here. I believe you understand how and why these joints work against earthquakes, so was hoping for a bit of guidance as I proceed. The Forbidden City buildings have stone walls that do collapse, and my goal is to design wooden ones that won't. What I am attempting to do is apply the dougong joinery to horizontal construction, tied into the vertical stability of the structure. I wish I could figure out how to email you.
There are two books that will help you with the design. One is called "The complete Japanese Joinery" published by Hartley & Marks publishers. The other is called "A Pictorial History of Chinese Architecture: A Study of the Development of Its Structural System and the Evolution of Its Types". You can design your patio and have consult with structure engineer.I know there are companies who are profession in constructing the tradition Chinese architecture work in China. (They recover lots of history building)Maybe they will give you some practical advices.
without knowing exactly the details of temple of heaven, i am wondering if it is a circular structure. Just speaking about the columns, is it a dodecagon? and it is peripherals and decors that make it circular -- just my guess.
Try this book. "A Pictorial History of Chinese Architecture: A Study of the Development of Its Structural System and the Evolution of Its Types". It has the measurement (proportion) of Dougong for ching dynasty.

But you can copy and past the letter "斗拱模型" on this website world.taobao.com/?spm=2013.1.0.0.7dd3fa8epk0h8h.Then you can see it hundreds of related item on sale.

Please get the m and n pronunciation right. 斗 is bucket， 拱 is arch， 昂might be extender 。 It is hard to understand if using Chinese technical name in English and expect foreign audiences would understand what you are trying to say. I love the content your video provides, but try to do some better translation if this is your major. It hard to translate all these in-depth because the topic itself is a complex architecture design.
Foolish Westerner. They know what a nail is but they don't want to use it because it is detrimental to the whole structure for wood expands but nails doesn't
I mean we’re still adapting Japanese and Chinese earthquake proof techniques into modern architecture but I guess u go? Lmao. Honestly a nail is literally hammering something in instead of understanding how to release the weight using your brain.

This is the first time I see the bracket style. :O!
i needed to see this like this for a seminar paper on palace architecture! Thank you for this demonstration!! was highly interesting and helpful!
And the brackets are so aesthetic as well!
Edit: like many things in their culture, japanese architecture directly 'borrow' from china but they dont mention that explicitly anywhere tho. If you know then you'd know
Thank you for this detailed description of the 斗拱 (dǒugǒng), I searched a lot about it.
Nice educational video! One thing I have to correct you that China has 4 wooden structures made in Tang Dynasty left. All of them are in my hometown-Shanxi province. Welcome people from all over the world come to visit. It will be a mind-blowing experience for you.
斗拱的作用，本意是将屋檐尽可能向外伸展，因为屋檐没有柱子的垂直支撑，所以所有的重力都是水平方向上的。而木材的水平承重能力是很差的，垂直承重能力却是比普通钢材还强，所以实际上斗拱解决一个尽量把水平方向上重力转化为垂直力的难题。
因此可以减少承重柱的数量。
至于抗震，这大概是个巧合，不用斗拱也能抗震，中式房屋，四梁八柱，框架结构。而框架之间的连接却是半活动的，所以遇到地震，地晃、房子也晃，其框架的半活动链接能卸力，不会被晃动撕裂，就像竹子柔韧却经得起大风一样。所以叫四平八稳、墙倒物不塌。

Better than the animated 3D Visualization. It felt so natural. Finally, today i did understand. Thank you meiniu.
So this is how "no nails" structures works....
Thank you !!
thank you, i built a 3D model of these connectors with your explanation. Very well explained, thank you very much. Very helpful

Excellent demonstration of an intriguing architectural technique. Thank you!
Excellent demonstration. Thank you!
You have explained everything very clearly....
Would you please state the size ratios of the wooden blocks?
By the way! Happy new year! Greetings from Greenwich: London! Go girl!👍
Thank you for your encouragement. Happy New year to you!!
You should add a SunMao and Dougong tag in your title!

most of these things are not documented but rather passed from master to apprentice, even for today.

真棒！看完立刻去买淘宝买了一个~
This is great! Thank you! How would a corner be constructed?
Very nice, thank you.
this is beautiful thank you
thanks. very informative.
Wow. We are neighbours. I'm in Acadia. Is this the design that is used in forbidden city? Is this the same that designed 10.1 earthquake? AMAZING!!!!

such a good and clear video, thanks a lot, very helpful
Thank you Georgi!
泥道拱和慢拱是有方向（纵横）区别的，不同方向的拱，开口位置不一致。
Thank you! I did learn
❤❤❤❤❤❤❤
Thank you so much
中国的斗拱抗震真的很强，为古人的智慧所折服！

I would really love to purchase the same model you have there. Can you share the information for ordering one?
讚喔
Can you break out like IKE .
I'm curious as to whether solid timber is needed for this architecture, or if you could make something like this from bamboo...
it is doable with bamboo, but it will look somewhat different, as long as it is one continuous wood grain
Thanks. Hope you are to use this in your designs. If so, please share.
You may watch those youtube videos that can give you some basic ideas. video F2H9UbIApYs and 6Ptzqcoo-mQ .

How would the bracket system work for a circular building like in the temple of heaven? does it have a different name?

The Chinese architecture was mostly built with wood or brick. If they do have any concrete bracket, it might be done very recently.
