DesignSafe Radio
We all have experienced natural hazards in our lives: earthquakes, hurricanes, tornadoes, tsunami, floods: they impact our society at the most fundamental levels. Through rigorous testing and outreach programs, the team at the Natural Hazards Engineering Research Infrastructure is committed to making sure the next natural hazard doesn't have to be a disaster for you and your family.

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

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

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.

Research engineer Alia Amer gives us an overview of ATLSS research center, core of the NHERI facility at Lehigh University. Amer shows examples of complex, large-scale tests – multi-hazard simulations – at Lehigh. The lab designs accurate, complete simulations, including soil-structure-interactions, of natural hazard events such as earthquakes and windstorms. Dynamic, quasi-static, and hybrid simulations!

Testing novel pressurized sand dampers at NHERI Lehigh with Nicos Makris
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.
