Gallopin Gertie

Brian Sweeney — Wed, 10 Mar 2010 04:28:36 +0000

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.

The Batch Photo Uploader allows you to upload multiple files with just a few clicks.
Depending on your package you can upload 100 photos at a time with just a few clicks.
Here’s how it works:

To use the Batch Photo Uploader you need to have a program called “FLASH” installed on your machine:
Get FLASH for free at: http://get.adobe.com/flashplayer/

- Log into your project as an Administrator
- Go to the Administration Page
- Click on “Photo Uploader – Batch”
- Select “Browse”
- Find the pictures you want to upload on your machine
- Using the “Ctrl” and “Shift” keys select the photos to upload
- Click “Open”
- Files will automatically begin to upload
- Note: When the page says “Processing Images – Please Wait…” just let the program run
- When all the uploads have completed you will be dumped into the “Add Photo Description” Page

Unemployment Graph

I’m a visual guy and things make much more sense to me when they’re displayed properly. For example everyone keeps talking about how the unemployment rate keeps going up. Latoya Egwuekwe created the following visual chart as a graduate student at American University showing the “Geography of Recession” by displaying the changing unemployment rates over time, it’s very well done.

Also thanks to @bwyman for pointing this out on Twitter.
