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.

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.
