Plus it's ideal for working over benches and stadium seating. The SkyScraper is perfect for churches, auditoriums, gymnasiums and other industrial applications. The SkyScraper is indeed the world's tallest a-frame ladder with a maximum height of 21-feet, making ceiling-height work simple and safe. Its multi-position functions make it a perfect adjustable ladder for stairs, chandeliers, skylights and other difficult locations in rooms with high vaulted ceilings. Where other ladders fall short, the SkyScraper from Little Giant goes above and beyond. The Little Giant® SkyScraper adjustable ladder helps you complete those tasks more easily. It is built in a ‘neofuturistic’ style that incorporates some elements of the traditional Japanese pagoda, and includes a central pillar attached to seismic dampers that can together absorb the energy of an earthquake.Little Giant 10121 21 Foot Aluminum MXZ Skyscraper Ladder The Skytree Tower in Tokyo is the second tallest building in the world. ![]() ![]() “Fortunately in Japan, architects are also educated about earthquakes, so engineers and designers are able to discuss with common sense.” “There are always big conflicts between us,” says Norihiro Ejiri, representative director of the Tokyo-based firm Ejiri Structural Engineers. “If you have each floor at exactly the same height and all the columns on an even grid spacing, the building will perform better in an earthquake.”īut often the designers of spectacular skyscrapers are reluctant to make those kinds of compromises, and tensions between the seismic standards required by engineers and the creative visions of architects are common. “Ideally what we want is to make the building as regular as possible,” says Lubkowski. Other methods involve the layout and design of the building itself. “That’s the minimum requirement.”Ĭomplex devices to absorb the energy of an earthquake and ease shaking aren’t the only way to make a building resilient to earthquakes. Unbeatable prices and exceptional customer service. “You design buildings to protect people’s lives,” says Ziggy Lubkowski, a seismic specialist at University College London.

This was a large earthquake – of magnitude 7.9 – that devastated Tokyo and Yokohama, and killed more than 140,000 people.įor earthquakes of a greater magnitude than this benchmark, preserving buildings perfectly is no longer the goal. The bar is set by the Great Kanto Earthquake of 1923. The second level of resilience is withstanding extreme earthquakes, which are rarer. The building should be so well designed that it can escape these earthquakes unscathed. For this magnitude, any damage that requires repair is not acceptable. There are two main levels of resilience that engineers work towards: the first is to withstand smaller earthquakes, the type that a building might see three or four times in its lifespan in Japan. All buildings – even if they are small or temporary structures – must be resilient to earthquakes in the country, says Jun Sato, a structural engineer and associate professor at the University of Tokyo. But the tower blocks of Japan are not ordinary buildings. ![]()
