In this paper, we develop a structural pre-evaluation and optimization technique for vault-like shapes. This implementation focuses on exploring design spaces in early design stages. The proposed technique approaches the problem of reducing the flexibility of the design space while advancing to later design stages for vault-like shapes. We start with a custom design space based on design intent. Then, we define a sampling criteria to study a reduced number of candidates. Later, the optimization process focuses on minimizing structural deformation values through shape manipulation. Results show a notorious enhancement for maximum deflection and displacement of the structure. Generally speaking, the shape optimization pattern is consistent with how vault-like shape works. All solutions reduce their span and boundary area while increasing the maximum height. Also, reaching maximum deformation values that are ten times better than the admissible final values on average.

This study is based on the development of a modeling technique for vault-like structure generation through topological manipulation. Currently, topology-driven form-finding has been implemented in tensile structures, but no further studies have been conducted for compression-only structures. The focus of this study is to approach the problem of highly determined vault shapes by their input topology. The technique operates at the topological level between vertices and edges to create an input 2D topology map. The particle-spring system uses such a map to simulate the resulting 3D mesh geometry. For testing purposes, we explore three generative approaches. The results show the effectiveness of the technique to manipulate the topological relationships that controls the generation of the funicular structures.
