    Full Interview with Jennifer Bridge

    Full Interview with Jennifer Bridge

    Full interview with Jennifer Bridge, principal investigator of NHERI University of Florida. Bridge explains the NHERI research facility, the Boundary Layer Wind Tunnel and its newest addition, the Flow Field Modulator.

    Combining Research from the Flow Field Modulator with the Boundary Layer Wind Tunnel

    Combining Research from the Flow Field Modulator with the Boundary Layer Wind Tunnel

    In this episode, Bridge discusses more research possibilities with the flow field modulator (FFM). As well as revealing effects of transient wind events on structures, it allows researchers to combine BLWT terrain-condition measurements with the FFM. So you could, for example, insert a structural model in realistic terrain and discover its performance during downbursts. Also, the FFM enables researchers to test larger models in the urban setting, called the urban canopy layer. Lastly, Bridge discusses the difference between NHERI’s two complementary wind-research laboratories. The UF facility enables fine-tuning of models, and the Wall of Wind at Florida International University enables full-scale testing. Bridge notes the importance of collaborations between facilities and funding agencies — for designing more a more resilient civil infrastructure.

    Flow Field Modulator Enhancing Wind Engineering Research

    Flow Field Modulator Enhancing Wind Engineering Research

    Professor Jennifer Bridge describes the flow field modulator, a new piece of equipment at the facility that greatly enhances the capabilities of the BLWT. The FFM is a bank of 319 very fast, individually controlled fans that can simulate transient events like wind gusts, downbursts, and thunderstorm winds. It can also replay wind events (called time histories) with data collected in the field, for example by the UF’s “storm chaser” team and its mobile weather towers. The facility is unique in its scale. Bridge explains how the FFM opens up wind engineering research to many new questions, with many new possibilities for discovering how different wind profiles affect structures.

    The Impact of Research Using the NHERI Wind Tunnel

    The Impact of Research Using the NHERI Wind Tunnel

    In this episode, NHERI at UF principal investigator Jennifer Bridge gives examples of the types of projects the facility enables. She describes wind-tunnel tests funded by FEMA, NIST and NSF that examined wind behavior on topographical models after Hurricane Maria struck Puerto Rico, many of which had direct impact on building codes. The facility is useful for researchers studying tornadic loads on residential structures — which are greatly affected by terrain conditions in wind storms. Bridge also describes a novel and super-efficient type of experiment called cyberphysical wind tunnel testing. These sophisticated tests allow for dynamic adjustments of the structure under consideration — in real time. Bridge says cyberphysical testing is the future of structural design.

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.
