Design Spaces of Structurally Pre-evaluated Funicular Shapes
Design Spaces of Structurally Pre-evaluated Funicular Shapes
Álvarez, Marcelo ; Bernal, Marcelo ;
Full Article:
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.
