Dr. Hua Chai presents Merged Force Diagrams at Advances in Architectural Geometry 2025
On November 18, PhD alumnus Dr. Hua Chai presented the paper titled “Merged Force Diagrams for Expanded Tension-Compression Design Space in Polyhedral Graphic Statics” at the Advances in Architectural Geometry (AAG) conference in Boston, featuring his PhD research at the Polyhedral Structures Laboratory. This paper presents a novel approach to structural form-finding using Polyhedral Graphic Statics (PGS), in which two or more force diagrams are computationally merged to generate new diagrams with complex topologies. Unlike conventional methods that directly construct force diagrams composed of convex, non-intersecting cells, the proposed merging strategy enables the creation of intricate force networks that include zero-volume and intersecting cells.
