Every day is an experiment!<\/strong><\/span><\/p>\n<p>If a major earthquake struck right now, would your home or office building be able to withstand it? In Japan, many buildings are designed with clever engineering tricks that help protect people from powerful earthquakes. During a visit to the National Museum of Emerging Science and Innovation (Miraikan), I came across a fascinating exhibit showcasing how buildings can survive earthquakes. Let me show you what I discovered!<\/p>\n<h3>When the Ground Turns to Jelly: The Mystery of Liquefaction<\/h3>\n<p>When sandy ground is shaken, the sand grains begin to move freely. Suddenly, the ground behaves almost like a liquid, causing objects sitting on top to slowly sink. This phenomenon is called <b>liquefaction<\/b>.<\/p>\n<p>Liquefaction is especially likely to occur during earthquakes in reclaimed land or sandy soil containing lots of groundwater. When it happens, buildings may tilt or even sink into the ground.<\/p>\n<p>One clever feature of this exhibit is that a string allows the ground to be reset immediately after each experiment, making it easy for visitors to try again and again. Take a look at the video below!<\/p>\n<p><iframe loading=\"lazy\" title=\"\u7802\u306e\u6db2\u72b6\u5316\u73fe\u8c61\u3010\u79d1\u5b66\u672a\u6765\u9928\u3011\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/drH32anR1hg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h3>Base Isolation: Separating Buildings from the Ground<\/h3>\n<p>Next, let&#8217;s look at three different technologies used to protect buildings from earthquakes. The first is called <b>base isolation<\/b>.<\/p>\n<p>The basic idea is surprisingly simple: place special rubber bearings between the building and its foundation so that the building is partially separated from the shaking ground.<\/p>\n<p>Even if the ground moves violently, much less of that motion is transferred into the building itself. In the exhibit, ping-pong balls were placed beneath a model building. When the ground was shaken, the building barely moved! In real buildings, these ping-pong balls are replaced by specially engineered devices known as <b>seismic isolation bearings<\/b>.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-37608 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/825b95761b63e312a6d533e4395d43a3.jpg\" alt=\"\" width=\"397\" height=\"241\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/825b95761b63e312a6d533e4395d43a3.jpg 1406w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/825b95761b63e312a6d533e4395d43a3-300x182.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/825b95761b63e312a6d533e4395d43a3-1024x622.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/825b95761b63e312a6d533e4395d43a3-768x466.jpg 768w\" sizes=\"auto, (max-width: 397px) 100vw, 397px\" \/><\/p>\n<h3>Earthquake-Resistant Structures: Standing Strong Against the Shaking<\/h3>\n<p>The second approach is <b>earthquake-resistant construction<\/b>.<\/p>\n<p>Unlike base isolation, this method accepts that the building will shake along with the ground. Instead of avoiding the motion, the structure itself is strengthened so it can survive the forces.<\/p>\n<p>There are two major design philosophies.<\/p>\n<p>One is the <b>rigid structure<\/b>, built to resist movement as much as possible.<\/p>\n<p>The other is the <b>flexible structure<\/b>, which bends gracefully like bamboo, allowing earthquake forces to be absorbed instead of resisted head-on.<\/p>\n<p>Both methods often use diagonal braces inside the frame, giving the building greater strength against sideways shaking.<\/p>\n<p><iframe loading=\"lazy\" title=\"\u5730\u9707\u3067\u5b9f\u969b\u306b\u4f5c\u52d5\u3059\u308b\u514d\u9707\u88c5\u7f6e\u306e\u6620\u50cf\uff3b2012\u5e7412\u67087\u65e5\u6771\u4eac\u9707\u5ea6\uff14\uff3d\u8d8a\u91ce\u5efa\u8a2d\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/niPgqKFRo1E?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-37609 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/d8824bdb4f41ba318914a8f59b554b26.jpg\" alt=\"\" width=\"266\" height=\"218\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/d8824bdb4f41ba318914a8f59b554b26.jpg 606w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2021\/04\/d8824bdb4f41ba318914a8f59b554b26-300x246.jpg 300w\" sizes=\"auto, (max-width: 266px) 100vw, 266px\" \/><\/p>\n<h3>Vibration Control: Slowing the Sway Like a Brake<\/h3>\n<p>The third technology is called <b>vibration control<\/b>.<\/p>\n<p>Rather than preventing shaking completely, this method reduces the motion\u2014much like applying the brakes to a moving car.<\/p>\n<p>One famous example is Shimizu Corporation&#8217;s <a href=\"https:\/\/www.shimz.co.jp\/solution\/tech039\/index.html\">Sloshing Damper<\/a>.<\/p>\n<p>Large water tanks are installed near the tops of skyscrapers.
