Structure Based Truss: Hearst Tower

Four week ago, me and my partners had a project of structure and form lecture. The project was to find a building that has a structure based truss. The other project was to find a building that has a structure based bulk or mass. In a big group, there are 18 people, we divided into two small groups, 'truss' and 'mass'. My group was in 'truss'. First week, we met our mentor. On that day, we're just divided as I said. Second week, we looked to three buildings, especially high rise building. And then one of those three alternatives, we took one to be seen by the mentor. After that, we decided to think what the materials for this model building. The building which I means in this title post is Hearst Tower in New York.

Third week, we decided to use balsa wood material for the main structure of tower and the old building and mica-look-like-ice for the windows. The mentor gave us an offer to try 3D print for this model. But after saw the printer, we, not only my group but also the other group that offered too, had a problem from the first use. It crashed for a while, even aborted. And it was really take a long long long time to create one millimeter, if I'm not wrong, it took about two hours. The other group who first to use had a ten centimeter high model to print, for just a module, so I always checked them to see the result and I asked them that they had to wait almost six hours to build their 3D model. wow...

Before the presentation day came, we decided not to use these 3D printer for our model. So, we took an initiative to follow the previous group just make a module. In the last night before the day, we had to wait about two hours to build a half centimeter model. For the building model, first, we made an elevation in CAD. This CAD was used for laser cutting the balsa wood, I had to make two elevation for this model. After that all, we bought two mica, but we used only one. To show floor plate in every stories of this building, I showed it with drawing pen and made some lines for every floor. So, we had four elevations structures, four sides window, four sides of the old building, and three elevation of core. The core was put in this model to show for comparison with the building.

Fourth week, it's time to show our model. We described a lot of things about it. We also described how to make this model and what obstacles that we past. The tools that we used, was cutter, drawing pen, ruler, scissor, and glue. The materials was balsa wood and mica-look-like-ice. It's simple then.
A little review about Hearst Tower building. It has 182 m high from bottom to top include the old building. The structure is a diagrid or it came from diagonal and grid. In one triangle that can we see is four stories high. This below is our model 3d of module and the building.
