Gallopin Gertie
I ran across one of my favorite engineering videos recording the collapse of the Tacoma Narrows Bridge, AKA Gallopin Gertie. I hadn’t seen this video since high school physics class.
- Construction Start: Nov. 23, 1938
- Construction Finish: July 1, 1940
- 4 months later it collapse on Nov. 7, 1940 – Caused by resonance vibration due to steady 42mph wind speeds.
The footage from November 7, 1940 was shot by Barney Elliott and his business partner Harbine Monroe who owned a nearby camera store in Tacoma – http://www.camerashoptacoma.com/.
Search YouTube for some more great videos on this collapse. Here is another one with some good information Tacoma Narrows Bridge Collapse.
The next bridge at this location was built with Stiffening Trusses instead of solid girders.
NREL
The National Renewable Energy Laboratory is currently building a new 220,000sf office building on their Golden, CO campus. It’s a ZERO Energy building meaning that it will produce the same amount of energy that it consumes, what a novel idea. Here’s a great video they’ve released with more information about the project.
Congrats to the team – Haselden Construction, RNL, Stantec, & NREL .
This project has been one of the “early adopters” using JobSiteVisitor to manage their job site photos. Haselden Construction has not only been using the program to manage their progress photos but they’ve also taken advantage of our web-cam integration.
We certainly could use more ZERO Energy projects like this across the country. It’s great to watch this project progress, what a wonderful building.
