Episode 1: Designing roofs to resist hurricane winds

Wind engineer Pedro Fernández-Cabán conducts experiments at the NHERI University of Florida wind tunnel, trying to discover how to prevent roof failure in low-rise buildings during hurricanes. In this episode he describes how he uses a special component of the UF wind tunnel that creates large and long-lasting wind gusts: the Flow Field Modulator.

Episode 2: StEER reconnaissance: how does it work?

StEER’s Stephanie Pilkington covers virtual damage assessments, travel and data-sharing logistics, and the business of deciding the types of damage data to collect. Field-mission complexities include coordinating w/local authorities and EM teams – and federal agencies like FEMA, the Army Corps of Engineers, and in the case of hurricanes, NOAA (the National Oceanic and Atmospheric Administration).

Reid Zimmerman, PE, SE

Technical Director, KPFF Consulting Engineers

Two approaches to engineering. For the NHERI Tallwood research project, practicing engineer Reid Zimmerman has been working with engineers in academia to produce a full-scale, 10-story wood building. The Tallwood structure is an experimental specimen that also looks and functions like a “real,” engineer-designed building. In this episode, Zimmerman talks about working with fellow engineers in the “applied research” capacity.

NHERI Tallwood Megaproject: a research and industry partnership. DesignSafe Radio host Dan Zehner catches up with Jeff Berman, NHERI Tallwood co-PI and earthquake engineer from the University of Washington. Berman explains how “mega-projects” like Tallwood simply can’t be done without significant collaboration between academia and industry experts at companies such as Simpson Strong-Tie, Swinerton and others with expertise in building construction, engineering, and mass timber design.

The NHERI Tallwood project is funded by the National Science Foundation, with support from many industry partners.

The shake table experiment is slated for early April, 2023. Follow the NHERI Tallwood project via the live video stream at UC San Diego: http://nheri.ucsd.edu/video/.

EPISODE 3

NHERI Tallwood: Testing earthquake performance of mass timber products

In our final episode with NHERI Tallwood co-PI Jeff Berman, we learn about some of the wood products used in this 10-story wood structure — such as mass-plywood panels, cross-laminated timber, and laminated veneer lumber. Industry partners like Boise Cascade and Freres Engineered Wood have donated many mass-timber components, wanting to discover if they are resilient to earthquake loading.

“This ten-story building has just about every type of mass timber that is currently made in it.”

-- Jeff Berman

NHERI Tallwood: Rocking walls in tall buildings. In our second episode with NHERI Tallwood co-PI Jeff Berman, we nerd out on “rocking walls.” How do these seismic-protection systems keep tall structures safe during earthquake shaking?

Jeffrey Berman

Professor of Civil and Environmental Engineering

University of Washington https://www.ce.washington.edu/facultyfinder/jeffrey-w-berman

U of Nevada earthquake engineer Keri Ryan shows us the external wall units on the 10-story NHERI Tallwood building: spandrels with ribbon windows and glass curtain walls, called mullions. Architects as well as engineers want to see how such non-structural elements perform under earthquake loading. During the March 2023 shake table test, more than 750 sensor channels will record behaviors like drift, acceleration, and joint slip and movement.

In this episode, earthquake engineer and #NHERITallwood co-PI Keri Ryan gets specific about #NHERITallwood nonstructural components: non-loadbearing walls — elements extremely prone to earthquake drift and damage. Ryan shows us the cold-formed-steel exterior-wall subassemblies and some of the innovative building components that can prevent non-structural deformations due to ground shaking.
