University of Florida Professor and research engineer Nina Stark dives into the logistics of post-hurricane data collection. In 2024, as part of the Nearshore Extreme Events Reconnaissance (NEER) team, Stark deployed to the west coast of Florida before and after Hurricane Helene. As she tells her story, we understand how reconnaissance deployments work – with so many uncertainties -- and how anyone can get involved. Stark urges students and early-career researchers to join an Extreme Events group

The seemingly outsized strength of cold-formed steel is not well-known. In this episode, earthquake engineer Ben Schafer, Johns Hopkins University, describes a research-industry collaboration with the automotive industry resulting in code changes for high-strength sheet-steel. Sheet steel has also been successfully tested in flooring systems. The upcoming CFS10 shake table test at UC San Diego is the high-rise building test for cold-formed steel.

Intro to cold-formed steel as resilient framing material

2025/04/14

Meet Johns Hopkins University engineer Ben Schafer, authority on cold-formed steel (CFS), also known as sheet steel or thin steel. Schafer explains that CFS is both strong and ductile – and therefore a remarkably high-performance structural framing material. Builders use CFS in a variety of ways – including as building-frame members, much like timber. Schafer’s research centers on CFS as structural framing to resist wind and earthquake loading. Thin and lightweight, CFS members comprise relatively

Homeowners Can Mitigate Wildfire Risk

DesignSafe Radio ·

2025/03/21

On the policy level, states first must define and map the wildland-urban interface; then states formally define risk-categories and mitigations required. Examples: clearing combustible material within five feet around the house and updating roof and siding with non-combustible materials. Fischer details these steps and ways research engineers seek to simplify risk-reduction for homeowners.

Collecting data after an urban-wildfire event

2025/03/20

To understand damage, engineers examine things like water-system piping. To understand the fire itself, they gather physical clues that help them determine “heat flux,” or fire intensity. They collect data such as distance and direction between structures, siding and roofing material, and the constituency of vegetation or structures adjacent the house.

Interview with Oregon State University research engineer Erica Fischer. As wildfires increasingly affect communities and civil infrastructure, structural engineers apply their expertise in interdependent lifeline systems and structures. Fischer says engineers are primed to investigate “urban conflagrations” in all phases, including community adaptation and mitigation. She cites research findings from the 2018 Camp Fire in Paradise, CA, which led to valuable new understandings about water pipeline

University of Florida engineer Brian Phillips describes the procedure for installing the Sentinel mobile weather station directly on the beach. Assembly starts with drilling a 20-foot auger hole. Once the foundation is secure, the team raises the 33-foot carbon-steel-fiber mast, fully instrumented. The setup resists wind and wave impacts. During the hurricane, the station sends data in real time to servers at University of Florida. This year, the team deployed the Sentinel during Hurricanes Helene
