• Cold-formed steel construction withstands seismic challenges better than expected

    Engineering researchers have provided the building blocks necessary for enabling performance-based design for cold-formed steel buildings, structures that have shown in shake-test experiments at the State University of New York at Buffalo to withstand seismic loading much better than previously expected. Light, strong, and easy to construct cold-formed steel (CFS) buildings are repetitively framed with light steel members and conform to well-defined seismic design codes. Until this latest research, however, engineers and builders significantly underestimated the seismic strength of cold-formed steel structures.

  • Electromagnetic disaster could cost trillions and affect millions. We need to be prepared

    In 1962, a high-altitude Pacific nuclear test caused electrical damage 1,400 km away in Hawaii. A powerful electromagnetic pulse (EMP) – created either by a solar storm or a high-altitude nuclear explosion — poses a threat to regions dependent on electricity, as such pulses could cause outages lasting from two weeks to two years. The main problem is the availability of spare transformers. Superstorm Sandy’s worst effects were in a single location. In the case of a big EMP surge, replacement transformers would be needed in hundreds of locations at the same time. The cost of an EMP pulse to the U.S. economy would likely be in the range of $500 million to $2.6 trillion. A report by the U.S. National Academies was even more pessimistic, guessing at a higher range and a multi-year recovery. Besides disrupting electricity such storms can also destroy satellites, disrupt GPS navigation, and make other parts of the infrastructure fail.

  • Home Depot faces lawsuit over Joplin, Missouri tornado deaths

    Home Depot is being sued in a wrongful death lawsuit by a woman who lost her husband and two children during a 2011 tornado in Joplin, Missouri. Edie Housel is contending that Home Depot is responsible for the death of her family due to the improper construction of the Home Depot store in which the three — along with five other people — were killed.

  • Erosion research could guide new preservation techniques

    Visitors to the Western Wall in Jerusalem can see that some of its stones are extremely eroded. This is good news for people placing prayer notes in the wall’s cracks and crevices, but presents a problem for engineers concerned about the structure’s stability. Research could guide development of new preservation techniques for weakened structures.

  • Texas coastal areas still unprepared for disaster

    When Hurricane Ike struck Galveston, Texas in 2008, leaving billions of dollars in damages and at least 100 people dead, residents knew that they were underprepared. Experts say that Texas coastal residents still are. Unlike Louisiana and New York after Hurricanes Katrina and Sandy, Texas has not developed a plan to protect its coast, and the state has failed to seek the same level of federal funding after Ike as the two other states sought after their hurricanes.

  • Rockefeller Foundation, USAID launch new Global Resilience Partnership

    The new initiative, funded with $100 million from the Rockefeller Foundation, aims to institute a new model for solving the interrelated challenges of the twenty-first century such as persistent and often extreme poverty, food insecurity, and climate shocks. By better aligning humanitarian and development planning, connecting the private sector with civil society and government, and crowdsourcing innovations and solutions, the Resilience Partnership will enable communities to prepare for, withstand, and emerge stronger from shocks and stresses in a way that reduces chronic vulnerability and keeps them on the pathway to development.

  • Tornado strength, frequency linked to climate change

    New research shows that climate change may be playing a key role in the strength and frequency of tornadoes hitting the United States. Though tornadoes are forming fewer days per year, they are forming at a greater density and strength than ever before. “We may be less threatened by tornadoes on a day-to-day basis, but when they do come, they come like there’s no tomorrow,” one of the researchers said.

  • Key U.S. coastal areas bracing for greater sea level rise challenges

    While climate change-related sea level rise is predicted to impact much of the country — whether directly or indirectly — over the next several decades, certain parts of the nation’s coasts are expecting to deal with more unique and intensive challenges.

  • N.C. science panel begins updating sea level rise report

    North Carolina officials announced last week that the state-appointed science panel supported by the Coastal Resources Commission(CRC) has begun updating a controversial 2010 sea-level rise report. The CRC oversees development in North Carolina’s twenty coastal counties. In May, the CRC votedto narrow the scope of the pending report to reflect the effects of sea-level rise for the next thirty-years, as opposed to the original timeframe of 100 years in the 2010 report. “I think the concept of doing it for 30 years will add credibility to the study,” Frank Gorham, the CRC’s chairman, said last Thursday. “People can think in 30-year timeframes.”

  • Complicating the task of quantifying earthquake hazards in the Pacific Northwest

    Nearly forgotten research from decades ago complicates the task of quantifying earthquake hazards in the Pacific Northwest, according to a new report from scientists at the U.S. Geological Survey, the University of Washington, and other universities. The report focuses on the Cascadia subduction zone — a giant active fault that slants eastward beneath the Pacific coast of southern British Columbia, Washington, Oregon, and northern California.

  • Assessing flood risk in a changing climate

    Growing consensus on climate and land use change means that it is reasonable to assume, at the very least, that flood levels in a region may change. In an argument grounded in an analysis of the inherent limitations of statistical analyses, the authors of a new study suggest that researchers’ typical starting assumption that flood behavior is not changing — even in the face of suspected trends in extreme events and knowledge of how difficult such trends are to detect — causes water managers to undervalue flood protection benefits, opening the door to unnecessary losses down the line.

  • Kansas, Missouri invest in tornado safe-rooms

    Last year’s tornado season prompted officials in Kansas and Missouri to invest heavily in safe rooms to shelter residents from future severe weather events. Schools tend to be popular choices for safe rooms, but new funding from FEMA is helping cities build safe rooms in other public spaces. The safe rooms are built to withstand tornado winds of up to 250 mph, and can survive being hit by a 67 mph projectile vertically or 100 mph horizontally.

  • New Bay Area hospital is constructed to withstand the most severe earthquake

    The new Stanford Hospital is being constructed to withstand the most severe tremors. The new hospital will be placed on 206 base isolators, enormous parallel steel plates with a sort of ball bearing suspension system between them, providing a buffer between the building and the moving ground. Each plate can move as much as three feet in any direction, allowing the building to shift up to six feet during seismic activity. Reducing horizontal movement during an earthquake minimizes the strain on a building’s vertical load-bearing structures. When completed, in 2017, the building will be one of the most seismically safe hospitals in the country, able to continue operations after an 8.0, or “great,” earthquake.

  • Scientists urge making critical infrastructure more resilient to solar storms

    Scientists predict the probability of a massive solar storm striking the Earth in the next decade to be 12 percent. The 23 July 2012 solar storm was pointed away from Earth and blasted safely into space, but had it been directed towards Earth, it would have produced the worst geomagnetic storm in more than four centuries, causing extensive electricity problems that could take years to resolve. Scientists are debating the amount of damage the grid would suffer during a massive solar storm. The U.S. National Academy of Sciencesestimated in 2008 that the damage and disruption could reach up to $2 trillion with a full recovery time between four and ten years.

  • California builds a sophisticated Emergency Response Training Center

    Citing the need for further emergency training, some Sacramento County officials have proposed a plan to construct a $56 million training facility for Californian emergency responders which would handle all types of training and scenarios.
