Lu shows how sheet-based structures are advantageous over conventional space frame systems. However, not all sheets are necessary as long as the load paths are preserved, and the system does not have kinematic degrees of freedom. To find a reduced set of faces that satisfies the requirements, this paper incorporates and adapts the matrix analysis method to calculate the kiematic degree of freedom of sheet-based structure. Built upon this, an iterative algorithm is devised to help find the reduced set of faces with zero kinematic degrees of freedom.
Innovation, Sustainability, and Legacy - IASS (International Association for Shell and Spatial Structures) Annual Symposium and Asia-Pacific Conference on Spatial Structures 2022 was held in Beijing, China from September 19th through the 23rd. In memory of Professor Yasuhiko Hangai (Japan, 1942-1998), a very active member of the IASS and its Executive Council, and in accordance with his career-long encouragement for young people, the Hangai Prize recognizes talented young researchers, designers, and engineers working in the field of shell and spatial structures. This recognition is achieved by selecting outstanding submissions to the Annual IASS Symposium in the form of research papers, resumes of design projects, or innovative ideas.
