    Snakeskin-inspired piles and tech transfer Featuring Alejandro Martínez

    Snakeskin-inspired piles and tech transfer Featuring Alejandro Martínez

    UC Davis professor Alejandro Martínez is moving his bio-inspired snakeskin piles into industry practice. The novel pile-surface employs “frictional directionality” characteristic of snakeskin. Field trials provided better than expected results, and Martínez is now working to get his new design into the hands of practicing geotechnical engineers. Much of his NSF-supported research took place at the NHERI at UC Davis Center for Geotechnical Modeling; the project is part of the NSF-funded Engineering Research Center, the Center for Bio-mediated and Bio-inspired Geotechnics, CBBG, at Arizona State University.

    Engineering with Evolution Featuring Alejandro Martínez

    Engineering with Evolution Featuring Alejandro Martínez

    UC Davis professor Alejandro Martínez explains how biogeotechnical engineers leverage solutions from lifeforms like worms, trees, and bacteria. It starts with fundamental, cross-disciplinary work with biologists. Then, at the UC Davis Center for Geotechnical Modeling (CGM), centrifuge tests fill an important gap between laboratory ideas and full-scale field tests. For instance, by replicating ground stress and increased gravity in a centrifuge, geotechs can model and test designs at greater soil depths and across soil types. The NHERI CGM facility functions as a testbed for the NSF-funded Engineering Research Center (ERC) called the Center for Bio-mediated and Bio-inspired Geotechnics, CBBG, based at Arizona State University.

    Biogeotechnics: Engineers leverage, learn from nature featuring Alejandro Martínez

    Biogeotechnics: Engineers leverage, learn from nature featuring Alejandro Martínez

    Geotechnical engineer Alejandro Martínez joins us to discuss a new and multidisciplinary engineering subfield called biogeotechnics. “Bioinspired” research examines and mimics ways that plants, animals and bacteria successfully interact with soil. For example: how tree roots successfully resist wind loads. “Biomediated” research uses biological elements to improve soil. For example, byproducts of certain bacteria can cement and desaturate soil — potentially preventing liquefaction in susceptible areas.

    Conferences, reconnaissance opportunities for NHERI grad students

    Conferences, reconnaissance opportunities for NHERI grad students

    Meet Nurullah Bektaş, engineering PhD candidate and research chair with the NHERI Graduate Student Council. He talks with Dan Zehner about the virtual GSC Mini Conference, slated for May 31, 2024. Bektaş, who is earning his PhD from Széchenyi István University in Hungary, encourages grad students in natural hazards get involved in sharing research and conducting post-event reconnaissance. He relates his own field experience helping householders in Turkey after the devastating 2023 earthquake series in Turkey and Syria.

    Sustainable Functional Recovery: A New Engineering Design Paradigm with Andre Barbosa

    Sustainable Functional Recovery: A New Engineering Design Paradigm with Andre Barbosa

    The novel Converging Design research project merges post-earthquake functional recovery with sustainability. Project PI Andre Barbosa discusses potential results from this effort, such as building code updates and new building products. Other tangible outcomes: successful industry-academia partnerships — and a cohort of engineering students who will take lessons about _sustainable functional recovery_ into the future. Barbosa welcomes individuals curious about sustainable design to contact or visit to the Tallwood Design Institute, located on the campus of Oregon State University in Corvallis, Oregon.

    Shake-Table Testing Earthquake-Resistant Building Components with Dr. Andre Barbosa

    Shake-Table Testing Earthquake-Resistant Building Components with Dr. Andre Barbosa

    Earthquake engineer Andre Barbosa joins us to describe the fascinating NHERI Converging Design project, currently testing earthquake-resilient building components on the NHERI at UC San Diego shake table. Barbosa describes U-shaped flexural plates (UFPs), which can deform and dissipate energy – and with post-tensioning rods, recenter. Also, the team is testing buckling restrained braces, which function like replaceable “structural fuses.” Lastly, the project is examining traditional steel moment frames coupled with braced frames that include energy dissipating (“yielding”) fuse-like elements. These tests will guide the future of resilient structural design in earthquake-prone regions.

Hurricane season in Florida

We just moved to Florida three years ago, this year has been crazy with the Number of hurricanes coming up the coast, what a great show for resources and information regarding hurricanes and preparedness! Thank you!!

In Depth and Fascinating

There's so much to learn about the incredible research going on around the world into improving safety and resilience of communities as they face natural hazards. This show has a well-curated stream of guests, is very timely in its coverage of current events, and is filling a cool niche. The content can be a bit heavy sometimes if seismic engineering, storm surge modeling, and the like aren't your cup of tea (certainly a strong cup of tea), but this podcast is deeply fascinating.
