The building was developed by Maguire Partners, who purchased the air rights above the historic library to add more height to the tower. Some counter-terrorism experts have expressed doubt that the plot was ever fully developed or likely to occur. "You don't want a building to be overly stiff because the more it fights the ground movement, the bigger the force developed inside the building," says Joseph.

Most new high-rises in the United States are built around a reinforced concrete core, a technique that Japanese engineers shun because they say it performs unpredictably in an earthquake. Japan sits in one of the most seismically active regions on the planet. Apples new headquarters in Silicon Valley was constructed with an acute awareness that the building sits in earthquake country. Unlike most American cities, Los Angeles has few tall buildings, with some lonely clusters of metallic skyscrapers in Century City and in a pocket downtown. While it may no longer hold claim to this engineering title, Taipei 101 still houses some of the most impressive seismic- and weather-resistant technologies ever designed. The goal of such a damper isnt to prevent swaying in general, but to instead attempt to control this movement.

Southern California is long overdue for a massive earthquake and this was known even prior to a newly identified fault in the area capable of creating a 7.4-magnitude earthquake. Steel and concrete are preferable to masonry and timber. Simply put, they are diagonal structures that are inserted into the rectangular areas of the frame. But while architects in The Big Apple have little cause to fear that their creations will be wiped off the map, their Californian counterparts must design for one of the most earthquake-prone regions in the world. David McNew/Getty Images North America/Getty Images, Pacific Earthquake Engineering Research Center. The US Bank Tower's terrifying Skyslide attraction is a glass slide that hangs off the side of the building, connecting the 69th and 70th floors.

The last major earthquake in the contiguous United States, which caused $20 billion of damage to the Los Angeles area, was a quarter of a century ago. These include: Aninterdisciplinary research group based out of the University of Bristol outlines both horizontal and vertical structural systems that strengthen resistance to seismic motion. As shown in this. The reason Los Angeles has traditionally avoided so-called super tall towers is because the city is located on the San Andreas Fault line, an active earthquake zone. "But the Eiffel Tower does not have high seismic loads," says Joseph. Cities wont be usable for many months, if not years, said H.
