Knitted composites are textile composite materials that consist of knitted textile reinforcement and polymer matrix. Knitted composites exhibit great design flexibility by allowing the customization of shapes, textures, and material properties. These features facilitate the optimization of buildings’ material systems and the creation of buildings with light weight and high material efficiency.
To achieve such a lightweight, material-efficient building structure with knitted composites, this research investigates the material properties of knitted composites and proposes a design process for building-scale knitted composite systems. In the material study, this research examines certain mechanical properties of the material and the effects of additional design elements. In the design exploration, this research explores the design workflow of the structural form, element arrangement, and knit distribution of the material system at the macro-, meso-, and microscales. The project of MeiTing serves as proof of the concept and the design workflow.
Architects and students of architecture today are less physically engaged with modeling and drawing representations of proposed things and increasingly rely on digital means and methods that are transforming their embodied interactions with actual materials. The result is that meaning, which makes architecture so central to our cultures, is being diminished. It is being replaced by a misplaced belief that „better” buildings and architecture result from increased use of digital tools. To recapture meaning will require a new design theory for architecture that builds on material engagement theory and the critical role of resistance and sensuous reasoning in the design process, which material has historically provided.
The assimilation of functionally graded (or multi-) materials into architecture is deemed to enable the rethinking of current architectural design practice and bring back material considerations at the heart of the early design process. In response, the paper outlines a functionally graded material (FGM) design workflow that departs from standard early-stage CAD, which is typically performed via computer elements devoid of materiality. It then analyses this workflow from a theoretical perspective, namely through Edwin Hutchins’ materially anchored conceptual blending, Lambros Malafouris’ Material Engagement Theory (MET) and John Searle’s concepts of intentionality. The aim is to demonstrate that due to the superimposition of material considerations that precede and succeed the CAD operation, working with material-less entities during early-stage FGM design is not logically sustainable. Additionally, multi-materiality allows for the questioning of authorship in the design process and leads to a repositioning of agency from the subject to the locus of engagement with digital materials and their affordances.
Material Engagement Theory (MET) theorizes artefacts as the emergent outcomes of non-linear processes of formation in which both human and non-human forms of agency are involved. It has proved a useful framework for exploring the architectural design process – which typically involves the mobilisation of multiple tools and materialities – but has not yet been applied to urban design. This paper argues that MET can be applied to the analysis of urban form, helping explain the distributed processes of urban formation. In sketching out an outline theory of urban material engagement, the paper facilitates a dialogue between MET and two theories of urban morphogenesis – SIRN and Space Syntax theory – which explain formal emergence in the urban surface and the urban grid, respectively. Exploring these theories’ analyses of urban formation – and the relationship between urban form and urban social behaviour – the paper outlines a theoretical synthesis which centres on the artefactual nature of urban form.
With the ascent of robotic architecture in academic discourse, we ought to reconsider how we understand building cognition. This paper revisits the Rietveld Schröder House from 1924 as a precursor of robotic building. With a built-in capacity for change, the building (now a museum and listed as a UNESCO World Heritage site) has a highly adaptable space plan that could be continually reconfigured by its occupants. The agency of change is shared between the house and its occupants, most notably Truus Schröder, who lived in the house for 60 years. This paper takes a material engagement approach to explore the relation between the occupant and the house and speculates how this might be a model for designers of contemporary and future robotic architecture to rethink concepts of autonomy and agency in building cognition.
Recently, 3D concrete printing (3DCP) technology starts entering the market from factories and laboratories, contributing to the creation of new construction methods and architectural forms. However, since the technologies of most 3DCP institutions are independently developed, there is a lack of consensus in terms of construction methods and development approaches in the industry. In this paper, based on 42 3DCP architectural works completed in last five years, a quantitative analysis was made to evaluate the impacts of the fabrication system on 3DCP building forms. The paper introduced three criteria, including Workspace Index, Geometric Complexity Index, and Tectonic Prospect Index, analyzing and answering the discussions about „adopting in-situ printing or prefabrication”, „using gantry printers or robotic arms” from the perspective of architectural form. By analyzing specific construction methods and design strategies in these projects, the research summarized three development trends, „mobile equipment, algorithmic structure, and intelligent construction”, which will affect the future development of 3DCP building forms. Finally, the paper discussed the advantages, limitations, and potential of four different 3DCP fabrication systems, expecting to point out the directions to further optimize each system and realize more diverse 3DCP buildings.
At present, the development and implementation of digital transformation are the keys to promoting high-quality industry development. The new digital fabrication method of robotic 3D printing is a research area being studied by many to tackle the issue of the declining productivity of traditional construction methods. Although many studies have been done, most of the current 3D printing projects are facing limitations in terms of scale. In order to bridge the gap, this article proposed a mass customization 3D printing framework system for large-scale projects. This article discusses how mass customization is made possible through the joint operation of the FUROBOT software and 3D printing hardware. By taking the east gate of Nanjing Happy Valley Plaza as a case study, the article demonstrates and studies the feasibility of the large-scale mass customization 3D printing framework system.
Code-Bothy examines traditional bricklaying using mixed reality technology. Digital design demands a re-examination of how we make. The digital and the manual should not be considered as autonomous but as part of something more reciprocal. One can engage with digital modelling software or can reject all digital tools and make and design by hand, but can we work in between? In the context of mixed-reality fabrication, the real and virtual worlds come together to create a hybrid environment where physical and digital objects are visualised simultaneously and interact with one another in real time. Hybridity of the two is compelling because the digital is often perceived as the future/emergent and the manual as the past/obsolescent. The practice of being digital and manual is on the one hand procedural and systematic, on the other textural and indexical. Working digitally and manually is about exploring areas in design and making: manual production and digital input can work together to allow for the conservation of crafts, while digital fabrication can be advanced with the help of manual craftsmanship.
The conventional building material palette has been proven limited in terms of adaptability to our current environmental challenges. Innovations in computational design and digital manufacturing have supported the broadening of biomaterial applications as an alternative. While biomaterials are characteristically responsive to stimuli such as temperature and humidity, their unpredictable behaviour is a hurdle to standardization and architectural utilisation. To examine the nexus between material formulation, computation and manufacturing, multi-biomaterial lattice structures were produced through an environmentally informed workflow. Customized biomaterial development resulted in three candidate biopolymer blends with varying levels of hydro-responsiveness and transparency. The computational strategy included a machine learning clustering algorithm to customise results and dictate material distribution outputs. To test the workflow, environmental data of solar radiation exposure and solar heat gain from a specific location was used to inform the material deposition via pneumatic extrusion for the design and digital fabrication of a deformation-controlled prototype of 350 mm × 350 mm. This led to a series of multi-biomaterial wall panel components that can be applied at architectural scale. In future, these techniques can support the incorporation of living elements to be embedded within the built environment for truly animate architecture.
In ancient Iran, in addition to defensive elements such as castles, fortresses, and fortifications, there were underground cities called dastkand. These cities had a shelter-protection function and provided safe space to protect residents when enemies attacked. In the scope of dastkand architectural studies, form typology, land-use typology, and provision of thermal comfort have been investigated in various studies but there is no study on dastkand defensive architecture, which is the main purpose of the present research. The research method is a mixed method (qualitative-quantitative). The required data are collected through a survey and then, analyzed using factor analysis in R method. The statistical population includes Iranian architectural heritage specialists and the sample size is estimated to be 165 persons. Sampling adequacy is confirmed based on the results of KMO test. The samples are selected using a non-probability sampling method. The obtained results indicate that ten factors have been effective in the architecture of Iran’s ancient organic shelters. In order from largest to smallest coefficient of variance, the factors include collective defense, multi-layered defense, environmental camouflage, path control, self-sufficiency, secret passage, sustainable architecture, residential values, covert surveillance, and cluster development.
Protecting large-scale heritage settlements from being damaged by fires has become increasingly crucial in developing areas that lack adequate legislation, emergency planning, and particularly efficient techniques. This study provides a systematic emergency assessment methodology for evaluating the accessibility of specific fire-fighting techniques to mitigate fire hazards in historical towns and examines how the integration of municipal and local fire services works. Specifically, this paper examines the accessibility of fire trucks, local fire services and the overall protection capacity. There are quantitative calculations of the obstruction degrees on main streets, the feasible moving distances of fire-fighting vehicles and firefighters at a given time, and the fire protection coverage and intensity in each town. Using these methods, this paper systematically assesses the fire resistance of three historical towns, Chuansha, Gaoqiao and Fengjing, as case studies. In contrast to previous studies focusing on the vulnerability of buildings in large historical settlements, this assessment method combines an examination of street networks and various emergency response techniques and is particularly applicable to developing areas.
This study identifies the types of areas in Seoul where foreigners are concentrated by reflecting the characteristics of their region of origin and residence in Seoul. Lack of cultural understanding and uniform policies for various immigrant communities are causing some social issues. Hence, this study aims to prepare the basic data from which the government can predict changes in ethnic areas and prepare policies suitable for each derived type. The 14 most populous immigrant communities in Seoul were investigated, and cluster analysis and ANOVA test were performed. This examination resulted in four immigrant community types. Each type has specific characteristics, which have influenced the creation and change of the built environment. Types 1 and 4 are collectivistic. These types gradually tend to change urban environments to emulate the environment in their region of origin. In addition, they make little effort to improve their degraded environments, and such areas become increasingly backward. In contrast, types 2 and 3 are individualistic and prefer to assimilate into a migrant region. The formation and change of the urban environment for each type can be predicted on the basis of these characteristics. From this information, the government can prepare an appropriate urban architecture policy for each type.
In performance-based architectural design optimization, the design of building massings and façades is commonly separated, which weakens the effectiveness in performance improvement. In response, this study proposes a hybrid massing-façade integrated design generation and optimization workflow to integrate the two elements in an evolutionary design process. Compared with the existing approaches, the proposed workflow emphasizes the diversity of building design generation, with which various combinations of building massing forms and façade patterns can be systematically explored. Two case studies and a corresponding comparison study are presented to demonstrate the efficacy of the proposed workflow. Results show that the optimization can produce designs coupling the potential of building massings and façades in performance improvement. In addition, the optimization can provide information that supports early-stage architectural design exploration. Such information also enables the architect to understand the performance implications associated with the synergy of building massing and façade design.
