If you live or work in one of LA’s many older concrete buildings and happened to read the Los Angeles Times recent story, “Concrete Risks,” your building, as swanky and detailed as it may be, may never be experienced in quite the same light. The report sounds the alarm on over 1,000 concrete buildings in the city and throughout the region that “may be at risk of collapsing in a major earthquake.”
California’s tallest residential-only tower and, according to some, the ugliest building in San Francisco has been given a new purpose following the installation last month of 72 accelerographs, or strong motion seismographs, within the building. Through a collaboration between the California Geological Survey, the U.S. Geological Survey, and Madnusson Klemencic Associates, the building’s structural engineers, the 641-foot southern tower of the One Rincon Hill luxury condominium development at the base of the Bay Bridge is now home to the “densest network of seismic monitoring instruments ever installed in an American high-rise,” the San Francisco Chronicle reported. These instruments, located at strategic points throughout 24 floors of the building, will provide “unprecedented” seismic data, which will in turn lead to better building codes and guidelines for structural engineers and future high-rise builders.
Mapping Disasters. In and around New York City, we were fortunate Tropical Storm Irene created little more than flooding, fallen trees, and electric outages, and that last week’s tremors left no damage in the city. If these rare northeast natural disasters are getting you down, perhaps it’s time to consider moving to the safest place in the U.S. to avoid natural disasters? A NY Times infographic hasfound just the place: Corvallis, OR. Cities in Oregon and Washington state top the list, while areas in Texas and Arkansas have the highest risk of earthquakes, hurricanes, droughts, and tornadoes.
Standing up to Earthquakes. Many of the east coast’s 19th century masonry buildings are not built to withstand a strong earthquake. How do those California skyscrapers withstand the west coast’s dangerous, powerful tremors? Gizmodo featured an array of earthquake-tech such as tuned mass dampers and roller bearings allow tall buildings to move with the earthquake and absorb shock.
Melancholy Utopia. The end of summer and beginning of fall will bring a flood of design events in European cities. Among them, more than forty designers will descend on Rotterdam on September 3rd to showcase their work throughout the city. The theme is Melanchotopia, an examination of the connections between melancholy and utopia, mourning and hope, said e-flux.
So Hurricane Tropical Storm Irene has come and gone, leaving most of New York City unscathed. It looks like some 700 trees were downed across the city and we’re sure a few patio chairs ran away from home, but luckily for the city, the storm lost its might as it raged toward Gotham. The Metropolitan Transportation Authority prepared for the worst before the storm, shutting down the city’s transit system electively for the first time (the system was also shut down after 9/11 and a power blackout). The agency has released an amazing set of photos of its preparation and cleanup after the storm including dramatic views of an abandoned Grand Central Station, mudslides, and flooded tracks. Take a look after the jump.
