The State of California has announced a new wave of grants through its Earthquake Soft-Story (ESS) program that will offer homeowners small $13,000 grants to be used in seismic retrofits. The grants apply to qualified homeowners in the San Francisco Bay Area and Los Angeles and could be a... View full entry
A group of researchers from the Polytechnic University of Valencia say they have discovered a means for protecting buildings from structural collapse. In a new set of building science experiments conducted in June 2023, they carefully studied animal neurobiology. El País tells us: “The team of... View full entry
César Pelli was a rising architect when he got the job of designing a new City Hall for San Bernardino.
[...] a push is on to renovate City Hall and restore it to use.
The lead architect: Rafael Pelli, son of César Pelli. [...]
“The idea is to preserve what’s great about it and make it better,” Pelli said of the building. “The bones of it are very good. We just need to bring it forward.”
— San Bernardino Sun
Chief of among the estimated $60 million renovation tasks is the work of replacing the building’s over 6,000 original windows, which Rafael Pelli says will now be double pane for improved insulation against the heat. The City of San Bernardino, California, shut down operations in the building in... View full entry
The five boroughs are home to more than 200,000 multifamily buildings made with un-reinforced brick and built from the mid-1800s to the 1930s, according to a city hazard plan. Many rowhouses across the city neighborhoods fall into this category.
Such masonry cannot bend or flex during an earthquake and would instead break or crumble. A strong earthquake could cause some buildings of this type to collapse.

Last week’s 4.8 magnitude tri-state quake wasn’t nearly as strong as the (estimated) 5.5 magnitude incident that occurred on August 10, 1884, and would have caused $4.7 billion worth of damage to the modern city, according to the New York Times. Experts have warned that the risk posed to... View full entry
The 7.4 magnitude that struck eastern Taiwan yesterday has provided evidence as to how the country’s reputedly strong building codes and regulations prevented significant losses of life and property 25 years after another tragic seismic event led to widespread change. "Taiwan’s earthquake... View full entry
Current seismic codes require public buildings to be built strong enough so they don’t fall down in a quake. Now, some emergency preparedness advocates want to raise the bar. Not only should essential buildings resist collapse in a strong earthquake, but also newly constructed schools, in particular, should be built so in the immediate aftermath they can be counted on to serve as relief centers. — Oregon Capital Chronicle
The article mentions the AIA Oregon chapter’s efforts to push lawmakers towards adopting more stringent building codes in preparation for a cataclysmic 9.0 Cascadia earthquake. Some relatively cheaper proactive measures, such as tsunami towers, are being enacted, but the 1,000 or so schools... View full entry
The LA Times recently debuted a useful map of seismic retrofit projects in major sections of the city months after official updates to the building code were enacted to address risks posed to soft-story and non-ductile concrete structures before 2033. The map was made by surveying available... View full entry
The rush to blame the destruction that ensued in the wake of this month’s devastating 6.9 magnitude earthquake in Morocco on rammed earth and the region's other traditional earthen construction methods is a flawed conjecture, according to an explanation penned recently by University of York...

Famous historic sites, low-income apartments and Twitter's headquarters all appear on a previously unpublished draft list of 3,407 concrete buildings in San Francisco that may be at high risk of collapse in a major earthquake, according to a copy of a city government document obtained by NBC News through a public records request. — NBC News
The city says the list is still a “preliminary draft inventory” of at-risk concrete structures, some of which were built after 2000, according to NBC. Who will actually pay for the mass retrofits still hasn’t been hammered out yet, leaving many to speculate as to its near-term feasibility... View full entry
UC San Diego has hosted the tallest full-scale seismic building test on an earthquake simulator. The LEVER Architecture-designed 10-story building, made of cross-laminated timber, was tested on what the organizers say is the world’s largest outdoor shake table.

In the wake of last month’s devastating earthquake in Turkey and Syria, Los Angeles County has identified some 33 important structures it says are the most at risk during a major seismic event of that magnitude. Last week, the Board of Supervisors published a list of at-risk properties owned by... View full entry
Los Angeles County’s Board of Supervisors voted Wednesday to approve a motion requiring all non-ductile, concrete high-rise structures in LA County to be given seismic retrofits within the next ten years. The motion applies to all incorporated communities in the county and must be codified by... View full entry
Why did so many buildings fall down? [...]
[Alanna Simpson] says the building codes in Turkey were updated again in 2018. But the country's "legacy buildings" are still vulnerable, and that goes for much of the rest of the world, too, she says. "It's a global problem."
— NPR
Of the more than 3,000 Turkish structures destroyed by Monday’s devastating earthquake, experts say the majority were concrete and masonry infill constructions built before Turkey updated its building codes in the wake of the 1999 İzmit earthquake that killed 17,000. A 2018 construction... View full entry
After Hurricane Fiona tore through Puerto Rico on Sunday [Sept. 18], roads in the small mountain city of Caguas—hit with more than 20 inches of rain—were underwater. Landslides washed away some streets. As on the rest of the island, the electric grid went down, and it wasn’t clear how many homes had been damaged or destroyed. But in two new prototype homes, the electricity stayed on. — Fast Company
The prototypes are single-family homes completely off-grid with electricity and potable water. They were designed by New York City and Puerto Rico-based Marvel Architects and paid for by nonprofit Acacia Network. The homes utilize hurricane and... View full entry
“The fact of the matter is that if a tsunami occurs tomorrow, we are going to lose all of our children,” said Andrew Kelly, the superintendent of the North Beach School District, which includes Ocean Shores. Mr. Kelly is one of a growing number of local officials who are calling for a network of elevated buildings and platforms along the Northwest coast that could provide an escape for thousands of people who might otherwise be doomed in the event of a tsunami. — The New York Times
Voters in the Washington state community of Ocean Shores will decide today on a measure that would install a pair of tsunami towers that can hold up to 800 people. Residents in the immediate shoreline region would have only ten minutes to escape potentially 100-foot waves propelled by a quake... View full entry
