Episode 3: Sustainable Functional Recovery: A New Engineering Design Paradigm
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.

Episode 2. Shake-Table Testing Earthquake-Resistant Building Components
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.

Hybrid simulation at Lehigh tests structural resilience In our second episode with NHERI Lehigh engineer Alia Amer, find out how this engineering lab performs real-time hybrid simulation, RTHS. This sophisticated, cost-effective testing method connects a numeric model of a substructure — with a physical model or device. Then researchers apply a natural hazard – wind, earthquake or waves – to test device resilience.

Makris episode 2
Testing novel pressurized sand dampers at NHERI Lehigh
Nicos Makris explains his innovative protective damper system made with pressurized sand, which obviates problems presented by traditional dampers that use oil. In partnership with the NHERI Lehigh experimental facility, Makris is performing component testing and developing the numerical model in preparation for hybrid simulation testing, also at Lehigh. The cyber-physical tests allow researchers great flexibility when developing large-scale engineering devices.

Dampers: shock absorbers for buildings
Earthquake engineer Nicos Makris joins us to discuss protective dampers, large-scale devices that function like shock absorbers for buildings and bridges. Dampers built into a structure absorb and isolate earthquake, wind, and traffic vibrations. Prof Makris reveals a new type of damper he’s designed that uses pressurized sand to address hydraulic failures in oil-based dampers.

Episode 3 Understanding major storms: key to coastal resilience
Understanding the behavior of coastal systems requires specialized researchers, including engineers, to instrument shorelines before a major storm — and to collect and analyze the resulting data. Woods Hole scientist Britt Raubenheimer reiterates the vital importance of federal funding, including NSF funding, which allows for multidisciplinary teams like NEER to perform nested, coordinated reconnaissance missions with NHERI engineers and agencies like USGS and NOAA.

Entender las grandes tormentas: clave de la resistencia costera
Comprender el comportamiento de los sistemas costeros exige que investigadores especializados, entre ellos ingenieros, instrumenten las costas antes de una gran tormenta y recojan y analicen los datos resultantes. Britt Raubenheimer, científico de Woods Hole, reitera la importancia vital de la financiación federal, incluida la de la NSF, que permite a equipos multidisciplinares como el NEER llevar a cabo misiones de reconocimiento anidadas y coordinadas con ingenieros del NHERI y organismos como el USGS y la NOAA.

Episode 2 NEER: Nearshore breakwaters and unintended consequences
Coastal scientist Britt Raubenheimer describes NEER’s data reconnaissance missions before, during, and after Hurricane Laura, which struck southwestern Louisiana in 2020. NEER data revealed that breakwater structures could slow storm-surge inundation – but then they would also retain floodwaters passing through it, significantly slowing recovery of the shoreland marsh.

NEER: Rompeolas cercanos a la costa y consecuencias imprevistas
El científico costero Britt Raubenheimer describe las misiones de reconocimiento de datos del NEER antes, durante y después del huracán Laura, que azotó el suroeste de Luisiana en 2020.
Los datos del NEER revelaron que las estructuras de rompeolas podían ralentizar las inundaciones provocadas por las tormentas, pero también retendrían las aguas de crecida que las atravesaran, lo que ralentizaría considerablemente la recuperación de las marismas costeras.

Episode 3: A new experimental facility for simulating windstorms
The National Science Foundation is funding a new, multihazard experimental facility called “NICHE,” still in the planning stages. As a co-principal investigator, Frank Lombardo is to helping to design methods for re-creating non-synoptic winds and wind profiles — storms of short duration and limited in space, like thunderstorms, derechos, and tornadoes.

Episode 2: Triangulating clues to tornadoes
Although dust devils can provide clues to tornado winds, U of Illinois wind engineer Frank Lombardo says tornadic behavior is still largely a mystery – and a bigger risk than researchers previously thought. He details ways wind engineers are piecing together answers, including simulations and damage surveys.

Episode 1: Wind engineers hunt dust devils
Dust devils! Understanding how these short-lived whirlwinds behave may help wind engineers understand tornadoes. In field studies, U of Illinois wind engineer Frank Lombardo collects data on dust devils, which occur more frequently – and are easier (and safer) to capture – than their high-powered relatives. Lombardo’s team has recorded more than 50 of these brief, 45 MPH windstorms. Find out how, where, and what the data show.

Wind engineer Pedro Fernández-Cabán conducts experiments at the NHERI University of Florida wind tunnel, trying to discover how to prevent roof failure in low-rise buildings during hurricanes. In this episode he describes how he uses a special component of the UF wind tunnel that creates large and long-lasting wind gusts: the Flow Field Modulator.
See it in action: a cell from the Flow Field Modulator. Hold your ears! https://www.youtube.com/shorts/ErHtAUU8Wns
Pedro Fernández-Cabán also describes specific ways roofs can be altered to redirect wind flow and reduce suction pressure – and roof damage. Parapets, for instance. Another goal for his project: use the UF Flow Field Modulator to develop a roadmap for wind conditions, revealing how different locations are subject to specific sorts of damaging wind fields – and to provide mitigation advice to builders and homeowners based on that roadmap.
