Article
This paper presents the development and application of a computational design tool that can be used to explore an AI-generated design space for the conceptual design of shell and tensile structures. An AI model was trained to extract geometric features from a dataset of 40 well-known design precedents of shell and tensile structures and to construc...
Article
This paper presents a theoretical framework for the implementation of Artificial Intelligence (AI) in architectural and structural design processes, and it is complemented by some practical applications. The aim is to demonstrate that AI can be used to simulate certain aspects of human cognition and can therefore be integrated into CAD software to...

Biodiversity is in a state of global collapse. Among the main drivers of this crisis is habitat degradation that destroys living spaces for animals, birds, and other species. Design and provision of human-made replacements for natural habitat structures can alleviate this situation. Can emerging knowledge in ecology, design, and artificial intellig...
Article
This paper presents a comparison between human-defined and AI-generated design spaces through simple optimisation applications. A design space is a formal expression of a design idea. It is constructed by selecting a set of variables, which limit the search for suitable solutions to a design problem within a specific range of options. Most computat...

‘Sketches of Thought’ is a human-machine collaborative design system based on Artificial Intelligence (AI). The first aim of ‘Sketches of Thought’ is illustrating an approach to AI-integration within the designer’s creative workflow. The system translates a hand-drawn architecture sketch into a photorealistic image that suggests a possible evolutio...

Acoustic shells for outdoor concerts are a specific subclass of passive acoustic systems aimed to amplify and equally distribute sound over an audience area in outdoor conditions. The objective of this paper is to describe an automated design methodology that takes advantages of Computational Morphogenesis to generatively inform an efficient acoust...

This study proposes an automated two-staged digital method to generate a feasible form-active gridshell given any arbitrary surface. It explores the behaviour of an external low-tech system in the forming process, and portraits a landscape of efficient solutions to address the trade-off between shape approximation and building costs. The product co...

This paper presents a deterministic method to design acoustic chambers for outdoor performances, and emphasises the benefits of a computational morphogenetic approach to the problem. It represents the newest outcome of a research program, conducted by ReS-Team and sponsored by VPM, on the development of the acoustic chamber ReS. The research work i...

This paper forms part of broader research collaboration between the design firm Gridshell.it, and the Department of Architecture, University of Naples that investigates the use of digital design tools in timber-based structures. This paper reports on the development of a digital-based application for form finding of timber post-formed gridshells. I...
Conference Paper

ReS is a sustainable hand-built temporary acoustic shell, developed since 2011 and built during the architectural workshop at Villa Pennisi in Musica in Acireale, Sicily, every year since 2012. It is the product of a research program started at the Department of Architecture (Diarc) of the University of Naples Federico II, Italy, which involves a t...

This research project aims to develop and apply numerical optimisation techniques, such as Genetic Algorithms, for the design and optimisation of free-form and innovative form-resistant structures. In particular, the research group has already obtained results on the following sub-topics: 1. Computational morphogenesis of free-form RC structures. Goal: develop an interface between CAD parametric models and FE solvers to run optimisation procedures during conceptual design; develop a strategy to interpret the results of a GA optimisation procedure, that is supporting the selection of sub-optimal shapes for shell structures. Current results: The Crematorium of Kakamigahara was selected as the first case study to develop an interface between Rhinoceros (where the parametric model of the roof was defined) and Ansys (which was used to perform FE analyses). The optimisation process was run by means of a GA. 2. Computational morphogenesis of acoustic folded-plate structures. Goal: develop a raytracing algorithm for rapid acoustic analyses of architectural spaces; test the raytracing algorithm for the optimisation of a hypothetical folded-plate roof structure for a concert hall. 3. Computational morphogenesis applied to historical case studies. First goal: study the emergence of unexpected topological variations of a parametrically defined composition of hypars. Current results: The Church of Longuelo was selected as the first historical case study to be redesigned starting from concepts rather than from the original spatial configuration of the building. Second goal: study the acoustic performance of Frei Otto’s tensile structures, therefore combining structural form finding with acoustic optimisation. Current results: Redesign of the Dance Pavilion and the five umbrella structures in Kassel (currently under development). 4. Geometry optimisation of free-form gridshells. Goal: rationalise the production and reduce the construction costs of structural and cladding elements. Current results: development of a GA and a VFDM for the optimisation of free-form glass gridshells. 5. Development of E-learning material for the Melbourne School of Design students. Goal: development of video tutorials and GH definition for Master’s students. This e-learning material includes tutorials for: surface discretisation, structural form finding, structural FE analysis, geometry preparation for fabrication.
