As I indicated in a previous post, the topic for my English 505 research paper is the collapse of the World Trade Center.Last night I watched a DVD titled World Trade Center: Anatomy of the Collapse (The Learning Channel, 2002). The filmmakers did a great job of explaining how the towers were designed and built, and used a lot of stock footage and computer simulations of the construction process. They also interviewed the project's lead structural engineer, Leslie E. Robertson, who is now a little old guy who seemed at the time of filming to be having a hard time accepting the tragedy of the WTC's collapse. For example, he kept referring to the towers in the present tense and would every so often have to stop and correct himself. He didn't seem to want to accept responsibility for the collapse, and he wouldn't even admit to feeling guilty (at least in so many words), but it was evident that he was devastated by it.
From other reading this week I learned that the WTC's architect, Minoru Yamasaki, was a first-generation Japanese American who grew up in the Seattle area but founded his firm in Birmingham, Michigan in the 1950s. Among his portfolio was the 30-story Michigan Consolidated Gas building in downtown Detroit, where there used to be a fine dining restaurant called the Top of the Flame. My boyfriend and I went there for dinner after my senior prom. One of the things I remember about it was the little flutter in the tummy I got sitting at a table right next to the floor-to-ceiling windows. It's ironic that Mr. Yamasaki -- who was afraid of heights -- designed buildings that must have given him the heebie-jeebies...but I digress.
I've done enough research to compose this preliminary thesis statement: The innovative design and engineering processes used to create the World Trade Center resulted in buildings that were taller, less expensive to build, and more profitable to rent than any that had come before. But the "tube" design, lightweight materials and untested construction techniques called for by the new technology failed completely after the impact of the aircraft. The structural integrity of the towers was destroyed, which made their collapse inevitable.
I'll let this simmer for a couple of days, and expand upon it in my next post. I may whittle the topic down a bit to focus on the building and safety codes that were in effect at the time the project was proposed, but I need to do more research first.
