080 – A Tool for Searching Active Bending Bamboo Strips in Construction via Deep Learning

As a popular material, the structural use of bamboo in architecture is commonly associated with active bending. As natural material, the deformation of unprocessed bamboo strips is affected by many factors such as the distribution of nodes, whose impact on deformation is difficult to precisely programme for each individual case and thus often cause discrepancies between generic digital simulation and construction. This research proposes a tool for searching active bending bamboo strips via deep leaning based on a multi-task neural network. The tool is able to predict both the number and locations of nodes suggested on bamboo strips according to a target curve as tool input. By approximating the prediction, users can find a strip that is most likely to deform into the desired geometry.

285 – Optimal Design of Wooden Pavilion Gridshell Structures in the Context of Architectural and Structural Collaboration

Tuesday 30 March, 09:45, Session 1B

Ewelina Gawell, Warsaw University of Technology, Faculty of Architecture

In the article two interacting aspects of collaborative design are described: shaping of the form and the rational use of materials. Form shaping will be analyzed on the basis of pavilions. Objects of this type, most often created for exhibition and educational purposes, are characterized by little functional limitations and by forms which can be freely shaped. The material aspect of this paper is concerned with the use of wood in contemporary construction. The first goal is to analyze the selected technical parameters related to the use of wood in the optimal shaping of gridshell structures in architecture. The second goal is to identify new opportunities for architectural and structural engineering cooperation in the context of generative digital tools. The possibility of creating new plugins for the existing generative modeling programs to improve the quality of collaboration will also be discussed. The paper is concerned with elementary research. I was able to achieve the set goals by means of theoretical analyzes based on the known literature as well as the analysis of the created objects and the accompanying research. The background for the work is a description of the selected trends of using natural wood as load-bearing elements in contemporary architecture and case studies of the selected objects that express the idea of form and material eco-efficiency.

111 – Future Coastal Cities with Biorock Infrastructure: Alternative Coastal Futures with Biodesign

Tuesday 30 March, 10:00, Session 1B

Despite having the potential of being a durable building material, Biorock, a form of calcium carbonate formed by the electro-accumulation of minerals dissolved in seawater, has never been applied on an architectural level due to its slow accretion process. This paper aims to plays out the possible narrative of this slow accruing material process in the incrementally submerged coastline of Jakarta, to empower local marginalized communities to self-construct a “new city” for habitation using Biorock, especially where building material resources may be limited. Urban cores with basic communal, housing and aquaculture facilities will be established using Biorock as the main building structure, which would be harvested in response to the gradual sea level rise.

Jennifer Gautama is a Master of Architecture (M.Arch) graduate student from the Singapore University of Technology and Design. This paper was written based on her M.Arch Design Thesis. Driven by the capacity of design to empower communities, enhance environments and improve quality of living, she strives to explore and find innovative solutions for cities. She is eager to work in an environment that embraces integrated design, innovative advanced construction processes and digital automation for current and future applications.

Christine Yogiaman is currently an Assistant Professor in Architecture and Sustainable Design at the Singapore University of Technology and Design. She also directs Yogiaman Tracy Design (yo_cy), a research and design practice that focus on the utilization of digital techniques along with contextual influences to create culturally embedded, affective work in Indonesia.

291 – Bio-Mineralisation and In-Situ Fabrication of In-Dune Spaces: Case Study of Thar Desert

Tuesday 30 March, 10:15, Session 1B

Medh Bansal, AA School of Architecture
Elif Erdine, AA School of Architecture

Desertification has made large productive landscapes in the South-west Thar desert redundant, subjected people to migration and induced a constant influx of sand into the region (Singhvi and Amal, 2014). The abundance of sand creates an opportunity to adopt an existing technique, Bio-mineralisation, to develop a sand based composite material which, when treated with a construction binder like sodium alginate, can be used for engineering purposes. The paper sets a theoretical framework to develop a fabrication mechanism with microbial-grout injections and propose the development of in-dune/underground assembly of habitable spaces. Each of the sub-components of material system, fabrication mechanism and In-dune structures are detailed, and evaluated to devise a hierarchy between them. Their interdependencies together inform design strategies, a phasing plan and global time scale for overall terrain transformation.

341 – The F8LD Mask: Parametrized On-Body Design for Personal Protection

Tuesday 30 March, 10:30, Session 1B

Andrei Nejur, Université de Montréal
Szende Szentesi, Technical University of Cluj-Napoca

The present research introduces a novel parametric approach for the construction of PPE, a face mask inspired from takeaway food packaging and kirigami techniques. The technique requires only foldable planar material with no gluing or binding. The design is customizable to the user’s face using an augmented reality application and automatic processing in the Grasshopper environment. Using the proposed workflow, a personal mask can be constructed from a cutting and folding pattern printed on any household 2d printer. This makes it one of the most affordable and fast techniques for artisanal PPE existent now.
