Structured becoming: evolutionary processes in design engineering
No full textComputational design techniques are changing the role of analysis tools in collaborations between architects and engineers. Digital feedback loops of synthesis, analysis and evaluation establish a ‘process of becoming’ in which structural solutions evolve and adapt to specific requirements. Highly differentiated constructions are possible when digital techniques are fully integrated in design and production. Klaus Bollinger, Manfred Grohmann and Oliver Tessmann discuss these novel paradigms in relation to recent projects from engineering office Bollinger + Grohmann.</p

Form, Force, Performance : Multi-Parametric Structural Design
No full textIn the 20th century, the classification of structures according to defined building typologies was central to engineering design. Here Professor Klaus Bollinger, Professor Manfred Grohmann and Oliver Tessmann of design engineers Bollinger + Grohmann challenge this preconception. By considering each structure as an individual case in point with inherently complex behaviour, they move away from the notion of a building being a variant of an established type. They further discuss this mode of working, in relation to their own recent projects, in terms of relevant methods and generative techniques, as well as the respective consequences that it has had on the relationship between force, form and structural performance.</p
Designing and prototyping of a novel textile-based 3D panel
No full textThe paper describes the designing and prototyping process of a novel textile-based building
component, named Textile Wall, conceived to quickly erect walls and roofs with a protective purpose
(humanitarian sheltering, flood protection, ballistic defense etc.), or simply to divide work and home
spaces. Textile Wall is an innovative foldable cell panel, lightweight and freestanding, made of semirigid
PVC foils and finishing textile layers. Stabilizing or insulating materials can fill its vertical cells.
The height and the dimension of cells, together with the membrane material (fabrics, mosquito netting, papers, composite fibers), can differ in relation to its final use and the expected durability. Man portable with a small logistical footprint, the use of digital technologies allows tailing the production of the Textile Wall in various, flexible and modular configurations. It can be deployed rapidly, without any engineering support; the easy set-up will encourage local users to repair or rebuild homes in case of disaster, taking into account own constructive and social background. The Textile Wall has been one of the results of the collaborative research project S(P)EEDKITS, founded from the European Union’s 7th Framework Programme - Security Theme (2012-2016), in which research institutes, universities, companies operating in the emergency sector and non-profit organizations have rethought shelters, medical care resources and other facilities provided in case of natural disaster and conflict
Innovative Cable Net Curved-Glass Photovoltaic Façade
No full textBuilding Integrated PhotoVoltaic (BIPV) facades have been present for decades in various forms and building application types. However, they have not yet reached their potential due to the strict technical PhotoVoltaic (PV) requirements, the design and simulation complexity, as well as their limited aesthetics, demonstrated by a lack of visual innovation and customization in comparison with other building elements. The main objective of this paper is to improve both overall visual effect and building performance through an integrated solar design approach. In order to address these requirements, this paper presents an innovative performance-based design methodology for a BIPV façade. The approach uses parametric design framework to define a typological set of BIPV modules, each with its particular performances, allowing module and performance variation across a façade surface. Therefore, each module can take a specific position in respect to the urban settings and indoor requirements, in order to optimize and improve the overall performance. Moreover, design criteria are not compromised, as this innovative methodology takes into account variable requirements with unique design system that lead to the consistent appearance, and embrace a paneling customization with just a small set of BIPV modules. This design concept has been demonstrated on a curved-glass BIPV façade that is mounted on a cable-net structure. The result is a high-performance optically dynamic façade, with a smooth and curvy appearance
Architecture and Structure – Just a Simple Love Affair
No full textBehind challenging architecture there is always a challenging structure. To achieve the optimal result in a design process, architecture and structure have to be developed together. Starting from the first planning phases, the cooperation has to be a fruitful dialog involving complex geometry programs and structural calculation tools. The result of such planning processes is exemplified in this paper presenting just 2 projects Bollinger+Grohmann realized together with two different architects, i.e. The Rolex Learning Center for Ecole Polytechnique Federate de Lausanne (EPFL) in Lausanne with SANAA, Tokyo, and the new building for the European Central Bank (ECB) in Frankfurt with COOP Himme (1) blau Vienna. The aim is to prove that there is no contradiction between new architecture and structure, but just a simple love affair
Success factors in the realization of large ice projects in education
No full textThere has been a long tradition in making ice structures, but the development of technical improvements for making ice buildings is a new field with just a handful of researchers. Most of the projects were realized by professors in cooperation with their students as part of their education in architecture and civil engineering. The following professors have realized ice projects in this setting: Heinz Isler realized some experiments since the 1950s; Tsutomu Kokawa created in the past three decades several ice domes in the north of Japan with a span up to 25 meters; Lancelot Coar realized a number of fabric formed ice shell structures including fiberglass bars and hanging fabric as a mould for an ice shell in 2011 and in 2015 he produced an fabric-formed ice origami structure in cooperation with MIT (Caitlin Mueller) and VUB (Lars de Laet)[4]. Arno Pronk realized several ice projects such as the 2004 artificially cooled igloo, in 2014[1] and 2015[2] dome structures with an inflatable mould in Finland and in 2016 one ice dome and two ice towers in Harbin (China) as a cooperation between the Universities of Eindhoven & Leuven (Pronk) and Harbin (Wu and Luo). In this paper we will present the motivation and learning experiences of students involved in learning-by-doing by realizing one large project in ice. The 2014-2016 projects were evaluated by Sanders and Overtoom[3] using questionnaires among the participants by mixed cultural teams under extreme conditions. By comparing the results in different situations and cultures we have found common rules for the success of those kinds of educational projects. In this paper we suggest that the synergy among students participating in one main project without a clear individual goal can be very large. The paper will present the success factors for projects to be perceived as a good learning experience.Structural Design & MechanicsEnvironmental Technology and DesignIndoor Environmen
