    Abstract [de]

    Im Jahre 2006 hat Mario Bellini den Architekturwettbewerb für die Sanierung der Firmenzentrale der Deutschen Bank AG in Frankfurt am Main gewonnen. Unter seiner Leitung ist in der Eingangshalle eine herausragende Skulptur entstanden. Die Sphäre – der architektonische Mittelpunkt des neu gestalteten Foyers zwischen den beiden Türmen, symbolisiert Stabilität und Stärke, aber zugleich auch Dynamik und Wandel.

    Der Entwurf des Architekten sah eine 16 m durchmessende Kugel vor, die mit Bändern umwickelt zu sein scheint und zwischen den beiden Türmen der Bank klemmt. Dieses Konzept wurde durch ein interdisziplinäres Team bestehend aus dem verantwortlichen Entwurfsarchitekt Giulio Castegini (Mario Bellini Architects), den Ingenieuren Oliver Tessmann und Mark Fahlbusch (Bollinger Grohmann Ingenieure) und Oliver Drawer der ausführenden Firma (Arnold AG) weiterentwickelt.

    Collaborative design procedures for architects and engineers2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This book argues for novel strategies to integrate engineering design procedures and structural analysis data into architectural design. Algorithmic procedures that recently migrated into the architectural practice are utilized to improve the interface of both disciplines. Architectural design is predominately conducted as a negotiation process of various factors but often lacks rigor and data structures to link it to quantitative procedures. Numerical structural design on the other hand could act as a role model for handling data and robust optimization but it often lacks the complexity of architectural design. The goal of this research is to bring together robust methods from structural design and complex dependency networks from architectural design processes. The book presents three case studies of tools and methods that are developed to exemplify, analyze and evaluate a collaborative work flow.

    Interlocking Manifold: Kinematically constrained multi-material systems2013In: Advances in Architectural Geometry 2012 / [ed] Lars Hesselgren, Shrikant Sharma, Johannes Wallner, Philippe Bompas, Jacques Raynaud, 2013, p. 269-278Conference paper (Refereed)
    Abstract [en]

    This research project investigates topological interlocking assemblies for architectural constructions. Topological Interlocking Assemblies are systems that unfold structural capacity by kinematically constraining and interlocking elements. Masonry is a simple example of an interlocking system: Bricks form a stable structure by brickwork bonds. Nevertheless mortar as additional rigid aggregate is needed to bind the elements. Assemblies with intricately interlocking modules in contrast, exclusively constrain their elements through inherent geometrical and topological properties. Topological interlocking systems were developed in material science. This project seeks to re-conceptualize the system within an architectural framework by embracing computational design, analysis and fabrication tools and procedures. The goal is to develop geometrical differentiated, reversible, force-locked systems and the processes and methods to design and manufacture them. The research started as a design studio at the Staedelschule Architecture Class (SAC) in Frankfurt.

    Structural Analysis as Driver in Surface-based Design Approaches2007In: Predicting the Future: 25th eCAADe Conference Proceedings / [ed] Joachim Kieferle, Frankfurt: eCAADe (Education and Research in Computer Aided Architectural Design in Europe) , 2007, p. 109-115Conference paper (Refereed)
    Abstract [en]

    This research argues for novel strategies to integrate structural analysis data in an architectural design approach. Instead of a linear procedure of synthesis, analysis and post-rationalisation a synthesis/analysis loop is installed that uses structural analysis data as design driver from early on. The approach is not aiming for a pure force-driven form-finding or optimization process but regards structural performance as one design criteria among others.

              Equilibrium between multiple parameters is aspired instead of a single-parameter-optimum. The research is conducted by a custom-made digital interface between a 3d modelling software and an application for structural analysis of space frames structures.

              Surfaces are translated into meshes with supports at user-defined nodes and then exposed to its dead load in the structural analysis software. The resulting nodal deviation is feed into an algorithm that steers the appropriate reaction towards the local stresses and deviations, taking into account the mesh topology, its supports and their position in the mesh. The initial mesh is optimized in shape transformed back into a double-layer surface model in the 3d software which evolves into an interconnected two-layer space frame. An instant feedback from synthesis to analysis and vice versa is installed. Analysing techniques migrate into the realm of synthesis.

    Abstract [en]

    Topological interlocking is a concept developed in material science. Solid modules form a structural system without the use of glue or mortar. Given fixed boundaries the elements constrain each other kinematically. This project seeks to re-conceptualize the system within an architectural framework by embracing computational design, analysis and fabrication tools and procedures. The goal is to develop geometrical differentiated, reversible, force-locked systems and the processes and methods to design and manufacture them. Students of the Architecture and Performative Design Studio (APD) at the Staedelschule Architecture Class (SAC) and the author developed the presented projects. The paper discusses the pedagogical approach of starting a design research studio from a very narrow material system. The research is continued at the School of Architecture of the Royal Institute of Technology (KTH) in Stockholm.

    Extremely heavy and incredibly light: Performative assemblies in dynamic environments2013In: Open Systems - Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia, CAADRIA 2013: / [ed] Rudi Stouffs, Patrick Janssen, Stanislav Roudavski, Bige Tunçer, Singapore: The Association for Computer-Aided Architectural Design Research in Asia (CAADRIA), Hong Kong, and Center for Advanced Studies in Architecture (CASA), Department of Architecture, School of Design and Environment, National University of Singapore, Singapore , 2013, p. 469-478Conference paper (Refereed)
    Abstract [en]

    This research addresses the design and negotiation of two kinds of assemblies that are similar in topology but fundamentally different in performance. Firstly, Topological Interlocking Assemblies (TA) are made of solid elements. Their overall structural integrity relies on each element being kinematical constraint by its neighbours. Secondly, Bell Kites, similar in topology but fundamentally different in performance these kites are made of clusters of tetrahedrons. While TAare heavy, massive and exposed to gravity Bell Kites are super light and dominantly driven by wind forces. These two instances formulate the opposing ends of a spectrum in which a new system, one that is capable of covering the full range of performance, is developed and re-conceptualized in architectural context. The research seeks designinnovation by scrutinizing systems that are not yet part of the architectural ecosystem. Mapping out their performative characteristics and developing their spatial and programmatic potential through conscious design moves explore the potential for architectural applications. The work presented in this paper is the result of a design research studio of the Architecture and Performative Design Class at the Staedelschule in Frankfurt.

    Abstract [en]

    In 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.

    Abstract [en]

    The overall performance of an architectural project results from balancing a complex network of multifaceted, interrelated requirements that originate from multiple sources.  In such a collaborative design process the authors conceive  of structure as an integral part of architecture.

    An approach to improve communication, collaborative design procedures and data exchange by a parametric 3d model and scripting procedures which act as an interface between architects, engineers and fabrication will be exemplified in this paper by a museum extension in Frankfurt/Germany.

    Der Planungsprozess von Tragwerken ist in den meisten Phasen von digitalen Technologien durchdrungen. Fast immer ist das rechnergestützte Arbeiten eine Optimierung bisheriger Prozesse, da repetitive Vorgänge automatisiert werden können und der Computer eine hohe Präzision liefert. Darüber hinaus verändern sich planerische Paradigmen wenn digitale Techniken konzeptionell und allumfassend  verwendet werden. Im Folgenden werden anhand einer Reihe von Projekten aus dem Büro Bollinger + Grohmann der konzeptionelle Einsatz computerbasierter Methoden in frühen Entwurfs- und Planungsphasen erläutert. Computer können viele Entwurfsvarianten erzeugen und bewerten und dadurch vorher nicht gekannte Lösungen auffinden. Tragwerke werden generiert, sofort evaluiert und für spezifische Situationen adaptiert.

    Prozessinnovation beim Konstruieren2008In: ARCH+: Archplus, ISSN 0587-3452, no 188, p. 88-91Article in journal (Other academic)
    Abstract [de]

    Die Tragwerksplanung bedient sich in der täglichen Arbeit Formalismen und Methoden, um Sicherheit und Vorhersagbarkeit von Tragstrukturen gewährleisten zu können. Formalisierung bedeutet, dass Denkprozesse in Handlungsprozesse überführt werden. Eine Reihe von Regeln stehen zur Verfügung, die die Handlungsalternativen einschränken und bereits geleistete Verständnisarbeit funktionalisieren. Einmal gewonnene Erkenntnis ist theoretisch für jedermann erlernbar und gehört zum ‘öffentlichen Denken’. 

    In unserer Arbeit mit Architekten werden die Rahmenbedingungen für Tragwerke aufgeweitet. Der Entwurfsprozess liefert Erkenntnisse, die zur Hinterfragung der Anfangsbedingungen führen und damit eine erneute Iteration erfordern. Tragwerke entstehen im Dialog mit allen Planungsbeteiligten. Der Tragwerksentwurf ist nur ein Aspekt in einem komplexen Netzwerk von Anforderungen, die ins Gleichgewicht gebracht werden müssen.

    Abstract [en]

    Computational 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.

    The Sphere – generate, calculate, fabricate2011In: Fabricate: Making Digital Architecture / [ed] Ruairi Glyn, Bob Sheil, Ontario: Riverside Architectural Press , 2011, 1Chapter in book (Refereed)
    Abstract [en]

    In 2006 Mario Bellini won the architectural competition for the refurbishment of the iconic Deutsche Bank twin towers in Frankfurt. Within the extensive environmentally-conscious renovation Bellini identified nine key areas to be modernized. In the lobby he proposed a strong visual focus point: A sphere, made from seemingly random criss-crossing metal strips, represents a fluid and dynamic core of the building. Bellini’s vision closely matched the client’s goals. Thus the image of the sphere was further developed by an interdisciplinary team of the architect (Mario Bellini Associati S.r.l), the engineers (Bollinger + Grohmann), and the contractor (Arnold AG). The process from the image to the real object is described in this chapter.

    Abstract [en]

    Collaborative design resembles a discussion or conversation. Ideas are bounced off the different members of a design team. Depending on the task and the point in time the engineer joins a design team different structural parameters contribute to an integrated solution. The paper will present different strategies we pursue involving geometry, topology and materiality. Geometry plays a major role for structural performance in large-scale structures and at the same time embodies the architectural design approach. Thus a solution which suits different requirements has to be negotiated. Topology of surface- and vector-active systems within a predefined shape or envelope can become the objective of evolutionary design processes where structure adapts to specific needs. Materiality is embedded into a larger context of material systems that include digital workflow and fabrication.

    Methoden und Werkzeuge der digitalen Tragwerksplanung2007In: Detail, ISSN 0011-9571, Vol. 12, p. 1484-1487Article in journal (Other academic)
    Abstract [de]

    Die Autoren Bollinger und Grohmann betrachten Tragwerke als integrale Bestandteile von Gebäuden. Der Tragwerksentwurf ist lediglich ein Knotenpunkt in einem mannigfaltigen Netzwerk, das Formen, Räume und Tragwerke hervorbringt, die nicht eindimensional optimiert werden können. Die Formen, die diesem multidimensionalen Findungsprozess entstammen, müssen analysiert werden, um Bereiche mit günstigem Tragverhalten darzustellen. Die dazugehörigen Tragwerke folgen dieser Form und passen ihre Wirkungsweise dem lokalen Kraftfluss an. Statt vorhandene Tragwerkstypologien zu variieren, kommen Mischsysteme zum Einsatz, die sich an spezifische Anforderungen anpassen können. Ingenieure benutzen genauso wie Architekten digitale Werkzeuge in ihrer Arbeit, jedoch unterscheiden sich die benötigten Daten voneinander. Das Architekturmodell wird durch Volumen und Oberflächen repräsentiert, während das Modell des Ingenieurs Achslinien und -flächen von tragenden Bauteilen benötigt. Diese Informationen werden auf Grundlage der Architekturmodelle im Ingenieurbüro generiert.

    Digital methods in structural design2009In: Innovative Design and Construction Technologies: Building complex shapes and beyond / [ed] I. Paoletti, Milano: Maggiooli Editore , 2009Conference paper (Refereed)
    Abstract [en]

    Bollinger + Grohmann conceive of structure as an integral part of architecture. The overall performance of an architectural project results from negotiating and balancing a complex network

    of multifaceted, interrelated requirements. As the design of structure is just one aspect within

    such a network of manifold relations, the appropriate structural systems cannot be found through

    single‐parameter optimisation. The specific forms derived through such a multiparametric design

    process need to be analysed in order to identify zonesP of favourable structural performance. The

    related structures adapt their load‐bearing capacities to the form and its particular local forces.

    Thus the resultant structures are highly specific, differentiated systems rather than variations of a

    defined typology. Nowadays, engineers are able to calculate complex load‐bearing systems. A

    structural design does not necessarily have to be broken down into its individual components to

    be assessed. The entire system can be investigated in all its parts together with the interactions

    between them.

    Abstract [en]

    The Sphere is a sculpture designed by Mario Bellini for the lobby of the Deutsche Bank head office in Frankfurt, Germany. A spherical network with a diameter of sixteen meters spans between the twintowers. This paper describes the ollaborative design process of architects, engineers and contractor. The various geometrical implications from design synthesis to fabrication and the exchange of information between the different parties are discussed. The concept of a spherical network was transformed into a series of sixty intersecting rings that act together as one sculptural and structural object. The ring configuration is derived from an evolutionary design process that includes geometrical and structural fitness criteria. Evolutionary design, structural analysis and fabrication demanded different geometrical representations that addressed the various constraints emerging during design and construction.

    Abstract [en]

    New structural mechanics insights have always had repercussions on the design procedures for engineers. The structural typologies resulting from these procedures privilege certain solutions while dismissing others. Timber bridge constructions of different periods exemplify this development. Computational design tools offer new possibilities for design procedures that overcome predefined structural typologies and evolve highly context sensitive and adapted structures. An evolutionary design approach for a vector active pedestrian bridge in Germany is presented in this paper.

    A design approach integrating architectural design with engineering by using programming as an adaptive tool2005In: Innovation in Architecture, Engineering and Construction, Volume 1 - Innovation in Design, Engineering and Construction / [ed] SARIYILDIZ S., TUNÇER B., Rotterdam: SOON , 2005, p. 73-80Conference paper (Refereed)
    Abstract [en]

    Instead of using engineering consultancy after finishing a design proposal and expecting solutions our pitch is to evaporate the professional demarcations of architects and engineers in order to synthesize the expertise of both professions. A collaborative approach with emphasis on a critical feedback is initiated in the beginning of the project.

    The use of NURBS surfaces as a powerful representation of double-curved surfaces ever so often compromises constructability. The paper describes how such a surface is translated into a population of parametric components. An adaptive space frame module is proliferated by using the surface parameterisation and a set of script routines. Component and form are developed simultaneously using design and engineering intelligence.

    This cooperative strategy between architects and engineers as well as the use of programming is exemplified by the project “augmentedFRAME” a design proposal for a landmark tower for Paris’ bid to organise the Olympic Games 2012.

    A composite system, made from layers of perforated plywood and latex film, together with ropes and rubber seals, performs as a flexible concrete formwork. In our research we investigated whether such a system could yield more than only one single repetitive concrete form. We sought to reduce the amount of material consumed by conventional formwork and we conceived formwork as part of the design process rather than a technical means during construction. We worked as a team of architects, structural engineers and artists and through the confluence of computational design, digital fabrication, material simulation and prototyping.

    This research argues for novel strategies to integrate structural analysis data in architectural design. Instead of a linear procedure of analysis, synthesis, evaluation and post-rationalization a synthesis/evaluation loop is installed which embeds structural analysis data as design driver from early on. The approach regards structural performance as one design criteria within a network of different requirements. An equilibrium of multiple parameters is aspired to instead of a single-parameter-optimum.The research is conducted via a custom-made digital interface between 3d modelling software and an application for structural analysis of space frames. The information exchange provides the basis for successive strategies within a collaborative design process of spatial roof structures: negotiation of an overall form and a multi-dimensional improvement of space frame topologies by a Genetic Algorithm (GA).

    From Structural Purity to Site Specificity: New Canopies for the Entrance Gates of the Messe Frankfurt2013In: Rethinking Prototyping: Proceedings of the Design Modelling Symposium Berlin 2013 / [ed] C.

    Abstract [en]

    This paper describes a structural design approach that seeks to replace structural purity and preconceived typologies by site-specific constructions. The process is exemplified by a canopy design for the Frankfurt fair. The competition-winning proposal is the result of a collaborative design effort of architects and structural engineers. In a computational design process the structure is optimized in regards to fabrications requirements and material consumption.  Beyond the particular project the design process is accompanied by a design tool development. Shortcomings in existing tools became obvious in the process and showed the need for in-house development of advanced collaborative digital design tools.
