Japan News, articles, and discussions in Tech category. Also a Japanese invention. Today’s Bridges and Future 2.4. The first such technology, called “rubber bearing,” was invented in New Zealand in 1977, and introduced to an office building there and a courthouse in the United States, Kani said, adding that it had a huge impact on the industry. resistant technology and seismic codes. With all of these revolutions, technology has also made our lives easier, faster, better, and more fun. Okumura Corporation’s specialty, a Seismic Isolation System, is installed. Few places have done more than Japan to define today’s technological landscape. The challenge, they say, is to ensure these new devices are reliable and deliver the optimum bandwidth while anticipating new regulations driven by worldwide environmental lobbying. The central feature of the seismic code revised in 1981 was the introduction of a two-phase earthquake design. Though quake-resistant technologies are widely disseminated in Japan, they are not originally from here. To denote the type technology, buildings are designated as either 耐震 (. By installing rubber bearings, composed of layered thin rubber and thin steel plates, under a structure, the building can move flexibly in a horizontal direction and has strong resistance to quakes. The shindo scale or JMA scale describes the degree of shaking at various points on the earth’s surface, not the amount of energy released by the earthquake. Authentication takes about one second, and the company says, improves with use… (July 2011) The system, which is also placed under a building, consists of a bearing pad on top of a curved surface. Thanks to seismic isolation techniques, the two buildings were to a great extent spared the intense force of the March event. The pores of membranes used … Seismic monitoring is one of the three waveform technologies used by the Comprehensive Nuclear-Test-Ban Treaty (CTBT) verification regime to monitor compliance with the Treaty. The 7 Biggest Technology Trends In 2020 Everyone Must Get Ready For Now. Top 10 Trending Technologies. “Before the quake, people wouldn’t accept seismic-isolation technologies,” he told The Japan Times in a recent interview. Although we’ve become accustomed to long international flights, jam-packed public transportation and diesel trucks that only get 20 mpg, the future of transportation promises to change all of that and much more — and it’s closer than many people realize. Later, another technology, called the “rotating ball bearing” system, was introduced. Some of this is attributed to improved processing techniques. The earthquake that struck Japan early this morning was the worst seen in that country for over 300 years (with a local magnitude of 8.9). Adobe Stock. Seismic waves, the same type of waves used to study earthquakes, are also used to explore deep underground for reservoirs of oil and natural gas. Preparing for the next big earthquake in Japan, JR East to Move Up Last Trains in Response to State of Emergency, My Experience Going to the Dentist in Japan: 4 Things I Learned, Looking for More Room to Work From Home in Tokyo? Apart from being delicious, Japanese food is on the whole extremely healthy, and incredibly diverse. People looking to buy or rent a property in Japan are often advised to look for a building constructed to the 1981 Shin-Taishin standard. Today the colleges and universities throughout France offer science and technology courses to help future scientists in the country. Image: Naigai-technos. The main earthquake-resistance building technologies used in Japan. Since the prescriptive seismic provisions revised in 1981 are still normally used in design offices in Japan, the paper will compare the 1981 Japanese seismic design provisions. This revolution has led to a system of globalization which has fundamentally changed modern society in both good and bad ways. Whether you’re looking for a more efficient way to eat your ramen or another frivolous cat toy to appease your feline overlords, cool Japanese products are always on trend. In Japan, wooden buildings have been used for many years, and people often say, “Traditional wooden structures, such as temples, are very resistant to earthquakes. Quake-resistant systems for housing are also widely used in Japan. “The development of quake-related technologies will never end,” he said. The Miyagi quake was measured at M7.8 on the shindo scale. Coast Preservation Technique 2.6.3. Hysteretic behaviors of these frames are investigated based on the test results. Production plants are also starting to introduce the system, after the major impact on Japanese industry of the two recent earthquakes in 2004 and 2007. The Sub-Committee first published “Design Recommendation for Storage Tanks and Their Supports” in 1984, and amended it in the 1990, 1996 and 2010 publications. “It is terrible for hospitals to collapse because they are supposed to be where victims can be helped,” said Kani. Ground shaking (pushing back and forth, sideways, up and down) generates internal forces within buildings called the Inertial Force (F Inertial ), which in turn causes most seismic damage. Researchers in Iceland have successfully used an existing fibre-optic communications cable to assess seismic activity. Browse our comprehensive listings and find your ideal apartment in Tokyo and Japan! This technology using rubber bearings is most popular in Japan and it is used around the world, according to Kani. What latest gadgets and gizmos are going to change your classroom? In a time of both misinformation and too much information, quality journalism is more crucial than ever.By subscribing, you can help us get the story right. No building can be designed to avoid all damages from an earthquake, regardless of the magnitude. They bend like willow to avoid building up stress.” We have actually seen wooden buildings swaying a lot in large earthquakes. Image. AND SEISMIC DESIGN TECHNOLOGY IN NEXT GENERATION by Shigeki UNJOH1), Takaaki KUSAKABE2), Sho-ichi NAKATANI3), Takeshi OHSHITA4), Yasuhiko WAKIZAKA 5), Kei-ichi TAMURA6) and Jiro FUKUI7) ABSTRACT This paper briefly describes the outcome of the earthquake engineering R&D in the 5-years R&D program for developing the road technology and the … This building has been retrofitted with giant shock absorbers. Most of the information appears in English for the first time. The charge circuitry is contained within the pack, so no special chargers are required. The emoji you used in your last email? “Considering the importance of sustaining corporate activities, companies don’t want to do business with those who do not take risk management steps,” Kani said. In future, China is likely to see more buildings introduce the quake-resistant system as a massive earthquake hit China’s Sichuan province in May 2008, Kani added. Important characteristics of the hysteretic behaviors, which are critical for the seismic performance, are discovered and compared between the four frames. Its overall goal is to make such structures more resistant to earthquakes. The key elements underlying Japan's industrial and technological rise have remained remarkably consistent over time. Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake.These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location. Japanese seismic code, but at the same time the previous seismic design provisions were kept as an alternative. The number of buildings with such new technologies will increase in the near future, Kani said. In a quake, this bearing pad slides on the curved surface to absorb tremors and support the building. In Japan, the Japan Meteorological Agency (JMA) measures seismic activity in units of shindo (震度, seismic intensity, “degree of shaking”). Top Photo: Daikai, Kobe. In addition, some buildings even employ a system to control shocks that uses computers. Now certain types of buildings in Japan are increasingly introducing the seismic-isolation system, such as hospitals, art museums, high-rise housing, embassies, and data centers that preserve customer information for banks, life insurers and nonlife insurers. In order to prevent collapse of buildings under large earthquakes while maintaining reasonable construction costs, structures are allowed to undergo ductile plastic deformations under current design and detailing methods. on the Japanese earthquake scale. Society 5.0 is Japan's concept of a technology-based, human-centered society, emerging through the fourth industrial revolution. Joe McKendrick Modern technology has paved the way for multi-functional devices like the smartwatch and the smartphone. Even well-designed buildings can suffer significant damage from a “small” earthquake, if they are built in an area where there is a very weak soil base. Institute specialists are trained in Japan, trained in modern technologies of processing seismic data. What do these three terms mean? This scale is used only in Japan and Taiwan. The network of sensors communicates with an air compressor, which, within a half second of being alerted, forces air between the building and its foundation. This amendment was introduced as a result of the devastating 1978 quake that struck Miyagi. The walls and/or load-bearing pillars are reinforced with specific stiffening materials to make them stronger against shaking. Shin-Taishin: If a building received its Certificate after June 1, 1981, it is called a shin-taishin building. Dam Technology 2.5.1. Example of taishin technology. This applies to your professional life as well. The education ministry warned June 16 that more than 7,300 school buildings are at high risk of collapse in the event of a powerful earthquake. Membrane chemistry: Membranes, through which water passes to be filtered and purified, are integral to modern water treatment processing. Artificial intelligence will transform big data collected through the Internet of Things into “new wisdom" and it will enhance human ability and expand our infinite possibilities, helping us enjoy more fulfilling lives. Many modern high-rise buildings use this technique to increase seismic resistance in an affordable way. The 1995 7.3-magnitude Great Hanshin-Awaji Earthquake wreaked havoc on Hyogo Prefecture. The 3D seismic survey acquired in the Dønna Terrace West area shows a significant improvement over other surveys acquired in the area with a dual source configuration. It works most effectively when used together with base isolation. This Week’s Top 5 WFH Properties, State-of-emergency to start on Jan 7th in Tokyo and 3 Prefectures: Suga makes official declaration, Japan to Stop New Entry of All Foreigners, Including Travellers from Countries with Special Agreement. Modern high-rise buildings use this technique to improve seismic resistance at a low cost. In addition, under the new standards buildings constructed after 1981 must be designed not only to withstand shocks to the building itself, but also with an eye to lowering the potential harm to life and limb from a quake. In the biggest natural disaster in postwar Japan, 6,434 people lost their lives — some crushed to death under buildings, others dying in the fires caused by the temblor. 8 Examples Of New Technology In Education. division of TAISEI Corporation, JAPAN Keywords: Construction techniques and technology, architecture, ... Modern Bridges 2.3.3. The 243-meter tall Tokyo Metropolitan Government buildings use various earthquake-resistance technology, including these giant shock absorbers. Current earthquake engineering practice for Japanese nuclear power plants is descried in JEAG 4601-1987, Technical Guidelines for Aseismic Design of Nuclear Power Plants.'' Kyu-Taishin: If a building received its Construction Confirmation Certificate before June 1, 1981, it is called a kyu-taishin building. Magnitudes are usually determined from measurements of an earthquake's seismic waves as recorded on a seismogram. ERGO uses sensors embedded in modern Android smartphones, meaning no additional hardware is required. Although all of the above methods are effective for making buildings more earthquake-resistant, menshin buildings are the best at lowering the total amount of shaking in the building and limiting shaking only to moderate, horizontal movements. Unlike other seismic intensity scales, which normally have twelve levels of intensity, shindo (震度, seismic intensity, literally "degree of shaking") as used by the Japan Meteorological Agency is a unit with ten levels, ranging from shindo zero, a very light tremor, to shindo seven, a severe earthquake. by TeachThought Staff. What will Tokyo’s second state of emergency mean? buildings have been measured to shake up to two-thirds less. The aforementioned seismic measures are used to calculate forces that earthquakes impose on buildings. Computers are increasingly faster, more portable, and higher-powered than ever before. Collapsed hospitals endanger patients who cannot escape the crumbling structures while the damaged medical facilities hamper treatment of the injured. These are the rioters who stormed the nation’s Capitol, Japanese obstetrician fights for 'confidential births' amid apathy, 'No need to feel inferior': China dating app helps raise awareness of LGBT issues, New Year Basho arrives with yokozuna absent and virus concerns rising, Directory of who’s who in the world of business in Japan. Indeed, it’s not just Japanese cuisine like sushi and ramen that shines in Japan. Someday, seismic data may even provide sufficient … AI-as-a-service . (2) 制震 (seishin, vibration control): The building is equipped with dampening devices (like shock-absorbers) designed to dissipate kinetic energy. Now the focus is on how to apply such quake-resistant technologies to existing buildings, including old structures, which requires a high degree of skill, Kani said. AEB systems use radar, cameras and lidar technology to assess the road ahead and work out potential collisions. (Specifically, buildings which received their Construction Confirmation Certificate (建築確認済書) before June 1, 1981 are subject to the old earthquake standards.) Underground facilities built in areas subject to earthquake activity must withstand both seismic and static loading. Of course, compliance to the 1981 standard cannot guarantee that the building will not suffer damage or collapse in a major earthquake. Thanks to quake-resistant technologies, Kurihara Central Hospital in Miyagi Prefecture, on the other hand, avoided a collapse in a big earthquake in Miyagi and Iwate prefectures in 2008, enabling the hospital to serve as the hub for rescuers. When a massive earthquake hit the western part of Japan more than a decade ago, a highway collapsed, railroads and telephone lines were partially cut, and many buildings were toppled.
