HANGZHOU SPORTS PARK NBBJ & CCDI Hangzhou Sports Park, (Hangzhou, China), Image Courtesy of [NBBJ] Project One will recreate and remodel the Hangzhou Sports Park by using Grasshopper parametric tools and definitions. The project consists of three main elements, large petals, small petals and the stage. The project will parametrically construct these three elements including their structural elements. The final product will allow the user to change the size of the stadium with maintaining the proportions of all the petals and their elements. Additionally, it will allow the user to, parametrically, manipulate the shape and size of all petals. The project will experiment with other Grasshopper tools, such as Kangaroo 0.99 and 2.00 in association with stress analysis components. The definition using Kangaroo components will convert static tensile petals to live tensile petals with anchor points that can respond to gravity forces and display the stress analysis
