Summary
The earthquakes in Türkiye and Syria have touched the hearts of 1.4 billion Chinese people. On the one hand, we hope that the local residents can hold on and refuel. On the other hand, we, the factories that make structural steel pipes, are lost in thought.
How can we reduce the damage caused by earthquakes? With the idea of whether there is a kind of building in the world that can resist earthquakes, we fell into deep meditation.
Through Internet inquiry, we finally saw these data.
There are really 10 earthquake-resistant buildings in the world. Today we will show you about them.
1.Citigroup Center
"Citigroup Headquarters" is the first to use the system to increase the stability of buildings - "tuned mass damper"
2.Japan Earthquake Resistant Building
An apartment built by Daikyo Corp, which claims to be the tallest in Japan, uses 168 steel tubes, the same as those used in New York's World Trade Center, to ensure seismic strength. In addition, the apartment also uses rigid structure earthquake-resistant body. In an earthquake of the magnitude of the Hanshin earthquake, a flexible structure typically shakes about 1 meter, while a rigid structure shakes only 30 centimeters. Mitsui Fudosan is selling a 93-meter-tall, earthquake-proof apartment in the Sugimoto district of Tokyo. The perimeter of the building is made of newly developed high-strength 16-layer rubber, and the central part of the building is made of laminated rubber from natural rubber systems. In this way, in the event of a magnitude 6 earthquake, the force on the building can be reduced by half. Mitsui Fudosan put 40 such buildings on the market in 2000.
3.Elastic building
Japan, an earthquake-prone area, also has special experience in this area. They have designed a "elastic building" with good seismic performance. Japan has built 12 flexible buildings in Tokyo. Tested by the magnitude 6.6 earthquake in Tokyo, it has proved to be effective in reducing earthquake disasters. This kind of elastic building is built on the isolation body, which is composed of laminated rubber rigid steel plate group and damper. The building structure does not directly contact with the ground. The damper is composed of spiral steel plates to reduce the ups and downs.
4.UK: automatic crack healing of earthquake-resistant buildings
British scientists are building a special house on a hillside in Greece, which can "heal itself" in an earthquake. As a leader in the research and development of special walls using nano-polymer particles, the "Nanomanufacturing Association" in Leeds, UK, is studying this "self-healing" wall with the support of the European Union. It is said that under the pressure of the wall during the earthquake, nano-polymer particles will flow into the cracks and harden to form solid materials, which will automatically fill the cracks of the house.
5.Greece: Smart shock absorption house
Since Greece is a country prone to earthquakes, the research on earthquake resistance has always been an important topic for local scientific researchers, and this new "smart shock absorption house" is the latest research result.
According to researchers, the biggest feature of "smart house" is its ability to "protect and repair itself". A variety of sensing devices are installed in the "smart house", which can also detect the slightest vibration, and can reduce and offset the earthquake vibration with the help of various devices in the house. The materials used in the "smart house" have the function of self-repairing. Once the wall cracks in the earthquake, the liquid repair materials can stick to the cracks and quickly solidify like glue, so as to prevent the collapse of the house. The indoor sensor can also quickly sense the change of temperature. Once the indoor temperature rises to a certain degree in an instant, the sensor will automatically notify the nearby residents and alarm the fire department through the Internet or satellite signal, so as to reduce the damage caused by the earthquake fire. It is reported that the first "smart house" will be built in a week.
6.USA: Ball Building
The United States has built a kind of shockproof "ball building", such as an electronic factory building recently built in Silicon Valley. Stainless steel balls are installed under each column or wall of the building, and the whole building is supported by the balls. The crisscross steel beams tightly fix the building and the foundation. When an earthquake occurs, the elastic steel beams will automatically expand and contract, so the building will slightly slide back and forth on the ball, It can greatly reduce the destructive force of the earthquake.
7. Floating anti-seismic residence
This huge "football" is actually a house called Barier made by Kimidori House in Japan. It can resist earthquakes and float on the water. The price of this special house is about 1390000 yen (about 100000 yuan).
8.Anti-seismic building design in ancient China
Different from the western brick-and-stone structure building, the traditional wooden structure building in China adopts the thinking of "subduing rigidity with softness" when resisting the impact of earthquake. Through various ingenious measures, the goal is to minimize the strong natural destructive force at the minimum cost.
The Chinese nation has not only wisely selected wood and other organic materials as the main structural materials since the beginning of civilization, but also developed and formed the world's longest history, longest duration, and most technologically mature structural system-flexible framework system. China's wood structure technology has a history of at least 7000 years. The traditional wooden structure in China has various advantages of frame structure, such as the effect of "the wall collapses and the house does not collapse", but its flexible connection makes it have considerable flexibility and a certain degree of self-recovery ability. In the Wenchuan earthquake, the walls of many cultural relics buildings were damaged to varying degrees, but the main structure still did not collapse, which is the performance of the seismic capacity of this flexible frame structure.
9.Yingxian Wood Tower
In addition to the above obvious techniques, a large number of other technical measures are also used in ancient Chinese traditional buildings, which are the key to the earthquake resistance of ancient buildings. The mortise and tenon joint is a very ingenious invention. Our ancestors began to use it as early as 7000 years ago. This kind of component connection method without nails makes the traditional wooden structure of China become a special flexible structure that surpasses the bent, frame or rigid frame of contemporary buildings. It can not only bear a large load, but also allow a certain degree of deformation, and absorb a certain amount of energy through deformation under earthquake load, Reduce the seismic response of the building.
Summarise enlightenment
1.Pay attention to the choice of venue
Buildings cannot be built on active faults, soft sediments and artificial backfilled ground.
2.It shall be designed according to seismic fortification requirements
Engineering structures that do not meet the requirements for seismic fortification will be seriously damaged under the action of seismic loads (forces).
3.Seismic design should be reasonable
When the building is designed, too few partition walls at the bottom, too large space, or the multi-storey brick building does not add ring beams and structural columns as required, or does not design according to the limited height, etc., will cause the building to tilt and collapse in a strong earthquake.
4.Reject "bean curd residue project"
Tofu slag projects often appear in those who abuse structural steel pipe materials in order to save costs, which is easy to become tofu slag projects. Therefore, Yuantai Derun Steel Pipe Manufacturing Group strictly controls the quality and strictly abides by it at all levels. It must not leave huge hidden danger to the project for temporary benefit.
5.The buildings shall be built according to the seismic fortification standards and constructed in strict accordance with the standards.
The editor finally said：
With the progress of the times and the development of civilization, natural disasters can also promote the innovation of construction technology. Although some buildings seem to make people laugh, in fact, all kinds of buildings have their own unique design concepts. When we feel the safety brought by buildings, we should also respect the ideas of architectural designers. The team of Yuantai Derun is willing to work with designers and engineers around the world to build more aseismic building projects. Welcome to consult. E-mail: sales@ytdrgg.com
