War on scale : models for the First World War battlefront

This essay traces the evolution and use of military scale models during the First World War. The application of such models by all belligerents is characterized by an enormous diversity in scale, context, construction method and purpose. Between the two extremes of a full scale replica of the Paris agglomeration and the tiny boxed miniature of a POW prison cell, a whole range of military models can be distinguished. On one hand, the model production can be considered part of a long tradition of military terrain modeling, as is evident in the examples of relief maps and training models. On the other hand, the rapidly changing technological and tactical developments during the Great War –such as strategic aerial bombing, camouflage and submarine warfare—require the creation of new types of scale models. During the last stages of the war, the encapsulation of the model as research object in a laboratory, looked at through optical devices and studied through model photography, demonstrates how this technological progress paves the way for a scientific approach towards warfare. The evolution of the models thus illustrates how war was waged on a variety of scales and that its theatre was far from limited to the battlefield itself

Analysing how constraints impact architectural decision-making

Architectural design projects are characterised by a high number of constraints. Along with planning, energy performance and fire safety regulations, current designers have to face constraining factors related to budget, acoustics, orientation, wind turbulence, accessibility for the disabled, and so forth. These constraints steer the design process implicitly and explicitly in certain directions as soon as architectural designers aim at satisfying design briefs. We aim in this article at analysing the impact of such constraints on the design process. At this end, we have studied four design sessions in a particular (student) design use case. In analysing these four sessions, we used linkography as a method, because this appeared to be one of the better options to obtain a more quantitative assessment of the design process. The linkography method was combined with an interview of the student design team, in order to check the correctness of our conclusions

Visualisation of semantic architectural information within a game engine environment

Because of the importance of graphics and information within the domain of architecture, engineering and construction (AEC), an appropriate combination of visualisation technology and information management technology is of utter importance in the development of appropriately supporting design and construction applications. We therefore started an investigation of two of the newest developments in these domains, namely game engine technology and semantic web technology. This paper documents part of this research, containing a review and comparison of the most prominent game engines and documenting our architectural semantic web. A short test-case illustrates how both can be combined to enhance information visualisation for architectural design and construction

Extending the design process into the knowledge of the world

Research initiatives throughout history have shown how a designer typically makes associations and references to a vast amount of knowledge based on experiences to make decisions. With the increasing usage of information systems in our everyday lives, one might imagine an information system that provides designers access to the ‘architectural memories’ of other architectural designers during the design process, in addition to their own physical architectural memory. In this paper, we discuss how the increased adoption of semantic web technologies might advance this idea. We briefly discuss how such a semantic web of building information can be set up, and how this can be linked to a wealth of information freely available in the Linked Open Data (LOD) cloud

Design thinking support: information systems versus reasoning

Numerous attempts have been made to conceive and implement appropriate information systems to support architectural designers in their creative design thinking processes. These information systems aim at providing support in very diverse ways: enabling designers to make diverse kinds of visual representations of a design, enabling them to make complex calculations and simulations which take into account numerous relevant parameters in the design context, providing them with loads of information and knowledge from all over the world, and so forth. Notwithstanding the continued efforts to develop these information systems, they still fail to provide essential support in the core creative activities of architectural designers. In order to understand why an appropriately effective support from information systems is so hard to realize, we started to look into the nature of design thinking and on how reasoning processes are at play in this design thinking. This investigation suggests that creative designing rests on a cyclic combination of abductive, deductive and inductive reasoning processes. Because traditional information systems typically target only one of these reasoning processes at a time, this could explain the limited applicability and usefulness of these systems. As research in information technology is increasingly targeting the combination of these reasoning modes, improvements may be within reach for design thinking support by information systems

The writings of Belgian engineer Arthur Vierendeel (1852-1940): homo universalis or contemporary propagandist?

During the last decade of the nineteenth century, Belgian engineer and professor Arthur Vierendeel - mostly known for the Vierendeel, a frame without diagonal rigidifying elements - published a series of books in which he expounded his views on the use of steel in architecture and engineering. Vierendeel described the structural possibilities of constructing in iron, and also theorized how this ‘new’ material should capture its own architectural style. Structural aesthetics is derived from rivets, proportions, tie rods, columns and covering strips whereas auxiliary aesthetics can be created through adding ceramics, other metals and decorative painting. Formal issues had to surpass structural considerations, or in Vierendeel’s words: “Pour les constructions métalliques les dimensions doivent être déterminées à priori par des considérations esthétiques et qu’après seulement il y a lieu de recourir à la formule mathématique.

The role of game rules in architectural design environments

'Experimenting' and 'observing' are crucial actions in architectural design thinking. They rely heavily on the representation environment used (e.g. sketching, scale models, sketch tools, CAD tools, etc.) and the 'game rules' at play in these environments. In this brief paper, we study the role of this representation environment in the overall architectural design thinking process. From this brief study, we indicate two design and implementation approaches to implement and design with such game rules in virtual design environments

Conversation and critique within the architectural design process: a linkograph analysis

Conversation and critique are central to architectural design practice as they function as tools for probing and further improving design ideas. We study the kind of design activities that take place in such conversation and critique within the architectural design process. We use linkographs to characterise the design process taking place during conversation. More precisely, we study conversations between design teachers and design students. In this article, an example design process is considered that takes place via a traditional face-to-face meeting. Using the resulting linkograph, we are able to assess the kind of design activity taking place during such sessions of conversation and critique

Architectural Information Modelling in Construction History

The past few years show a significant increase in the usage of three-dimensional modelling and semantic description techniques for architectural research purposes. Where this increase has already shaped today’s design and construction industry, research in architectural and construction history can still improve its work methods and results through these techniques. Therefore, we propose a new conceptual approach for Architectural Information Modelling (AIM), which aims at describing historical information in construction and architecture directly related to design information and design practice. This paper will give an introduction into existing 3D modelling techniques and semantic description techniques, continuing with how these techniques are applied in the AIM approach. This investigation of 3D modelling and semantic technology shows promising results. However, in order to integrate these techniques into an AIM framework, more work is needed. Future work in this research project will therefore explore in further detail the semantic description scheme proposed below and the implementation of a proof-of-concept

Increasing information feed in the process of structural steel design

Research initiatives throughout history have shown how a designer typically makes associations and references to a vast amount of knowledge based on experiences to make decisions. With the increasing usage of information systems in our everyday lives, one might imagine an information system that provides designers access to the ‘architectural memories’ of other architectural designers during the design process, in addition to their own physical architectural memory. In this paper, we discuss how the increased adoption of semantic web technologies might advance this idea. We investigate to what extent information can be described with these technologies in the context of structural steel design. This investigation indicates significant possibilities regarding information reuse in the process of structural steel design and, by extent, in other design contexts as well. However, important obstacles and question remarks can still be outlined as well
