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.

Makris episode 1

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.
