In the design of large-span buildings, the form of the structure plays a decisive role in the final architectural form. In this project, we compound serveral simple structure paradigms to form a complex structure that can fit the shape of the leaf, and then use parametric methods to analyze the structure force, and continuously optimize and improve the structure to obtain the final result. In the end, the curved shape and the organic topography complement each other and stimulate the vitality of the campus.
