1.013: Senior Civil and Environmental Engineering DesignClass, 2014
As part of their senior capstone design class in Civil and Environmental Engineering, students completed a 3-week exercise to design, fabricate, and test a scale prototype of a sensor tower, with the goals of minimizing cost and embodied carbon while meeting strength and deflection performance goals. Students designed their towers with the help of hand calculations and digital tools, including structureFIT and commercial structural analysis software. They selected materials from a catalog of options that included steel, aluminum, wood, carbon fiber, FRP, and 3D-printed ABS plastic, with a focus on tradeoffs between cost and structural performance. Fabrication of physical prototypes involved a combination of traditional and digital making techniques, with an emphasis on connections and interfaces between materials. Finally, the structures were load tested to investigate failure modes and reveal differences between calculated and actual performance.
