This is a visioning study down by the Perkins+Will San Francisco Office. The designers were Bill Katz and Jess Austin (me!) Andrew Wolfram was the managing principal and Arup provided engineering consultation.
This first scheme was developed to be a lighter weight structure that sailed above the current Diridon Station while creating a new space for The Proposed High Speed Rail. The structural diagram for this option was fairly simple, the large white members held themselves vertically with some basic columns helping out. The smaller cable like wire would provide the lateral support and respond to each unique loading condition. I used grasshopper to build the majority of this model hoping that any sizing or stress information we received from Arup could be integrated into the model. Thereby creating a feedback loop between the design and the structural requirements. Because this project was so short (two weeks!) we didn’t have the chance, but I know it can be done. The incredibly talented Ripon De Leon is updating our ColoniaTecne Project based on Buro Happold’s input.
This second scheme had some input from Andrew Tsay-Jacobs in our office. He went to engineering school and received three degrees before going to Columbia for his March; which is to say I think he’s very interesting. While he didn’t run any analysis or come up with any hard numbers we did sketch out a diagram that we think could work. Essentially the large columns are a vertical cantilever that triangulate at the bottom and there are smaller members that create an overall diaphragm for the roof. All very conceptual but this model was also made with grasshopper in the hopes that each member could be optimized. I am not publishing those definitions because they are a mess, and I think Perkins+Will might own them because I made them there. I hope you like it!
