Abstract

The objective of this study is to propose methods to design and analyze a catenary shell using a computer program without experiments and measurements. The intial idea stems from Pendergrast's study, but his method should be improved. In this study, the process of making catenary shell using computer was reproduced by Grasshopper script. In order to enhance credibility, two models from Grasshopper script were analyzed by SAP2000; one was just a square-based catenary shell, while the other was the re-created shell originated from the Naturtheater $Gr{\ddot{o}}tzingen$. The outcome of analysis was reasonable.
