This report tells the story of the structural design process of the LilyPAAAAD tower. The highlights of this process include precedent studies, 2-D structural analysis studies, hand calculations, and drawings. Precedent studies gave insight into unknown possibilities and helped discover how other engineers achieved their design goals. Projects like Sendai Mediatheque and the HSBC Tower are innovative solutions to unique design criteria. 2-D structural studies revealed how the braced frame and outrigger systems worked. By changing member stiffness and studying the load path, the members that contributed the most to resisting the load could be identified. Hand calculations were essential for checking the results of the computer model. Simplified calculations helped to pinpoint elements that needed to be adjusted and determined if the model was accurate. Lastly, drawings were used to communicate the design and illustrate the story. Through this process, the structural system of the LilyPAAAAD Tower was created, analyzed, and depicted.
