Form, Force, Performance: Multi‐Parametric Structural Design

Bollinger, Klaus; Grohmann, Manfred; Tessman, Oliver

doi:10.1002/ad.637

“…The geometry of form in the concept design has been achieved by contouring and traced using the Rhinoceros freeform modeler. Mutsuro Sasaki, who developed the concept of "Morphogenesis Flux Structure" [67], whilst working with SANAA, Bollinger + Grohman, and Arup, implemented this new shape-analysis approach for waving slabs, which he called Extended ESO (EESO) [68,69]. The Evolutionary Structural Optimization (ESO) can also be understood as an evolutionary design tool, one that is not limited by the availability of calculation and methods of analysis.…”

The Anthropocene thesis poses new challenges to human activity on the planet. These challenges also apply to the built environment. Climate change will increase existing threats, and create new ones, for both human and natural systems. Above all, the built environment is expected to provide structural stability, access to water necessary for life, and safe production of clean energy. This research-by-design was focused on designing an adaptive built environment for Anthropocene societies and the maintenance of their well-being, and on envisioning and conceptualizing new architectural solutions based on multidisciplinary knowledge and CAD parametric design methods and tools. The conceptual designs are the result of these studies. These visions show how wind loads can be reduced, water can be stored, diverse energy sources can be integrated into one work of architecture, and thermal comfort can be provided to support local communities and the life of the environment in the belief that the coexistence of species on the planet will happen. They also illustrate how humanity will be able to use the Earth and its atmosphere as an energy producer and conductor and create a global, wireless, non-commercial energy network, accessible to all.

“…In each case, a large number of requirements can be expected to be satisfied by the structural system, which do not only include load bearing capacity and safety, but also other interrelated aspects. With this respect, Bollinger et al (2008) intend the structure as an integral part of architecture, in which the overall performance balances a complex network of multifaceted, interrelated requirements; this makes each structural design being somehow unique (Billington, 1983). Among the many requirements, some are here considered based on their common occurrence.…”

“…An example of such approaches can be found in Winslow et al (2008), where a method to map grids into a given surface is described and integrated with an optimization process to locate the structural nodes (Winslow et al, 2010). With a similar goal, Bollinger et al (2008) analyse and identify the regions of given shapes that can be altered to satisfy the structural performance without affecting other architectural performances. Such methods have been consistently used for large projects, such as for the structural design of the BMW Welt project by Coop Himmelb(l)au.…”

Using engineering performance evaluations to explore design alternatives during the conceptual phase of architectural design helps to understand the relationships between form and performance; and is crucial for developing well-performing final designs. Computer aided conceptual design has the potential to aid the design team in discovering and highlighting these relationships; especially by means of procedural and parametric geometry to support the generation of geometric design, and building performance simulation tools to support performance assessments. However, current tools and methods for computer aided conceptual design in architecture do not explicitly reveal nor allow for backtracking the relationships between performance and geometry of the design. They currently support post-engineering, rather than the early design decisions and the design exploration process. Focusing on large roofs, this research aims at developing a computational design approach to support designers in performance driven explorations. The approach is meant to facilitate the multidisciplinary integration and the learning process of the designer; and not to constrain the process in precompiled procedures or in hard engineering formulations, nor to automatize it by delegating the design creativity to computational procedures. PAS (Performance Assessment Strategies) as a method is the main output of the research. It consists of a framework including guidelines and an extensible library of procedures for parametric modelling. It is structured on three parts. Pre-PAS provides guidelines for a design strategy-definition, toward the parameterization process. Model-PAS provides guidelines, procedures and scripts for building the parametric models. Explore-PAS supports the solutions-assessment based on numeric evaluations and performance simulations, until the identification of a suitable design solution. PAS has been developed based on action research. Several case studies have focused on each step of PAS and on their interrelationships. The relations between the knowledge available in pre-PAS and the challenges of the solution space exploration in explore-PAS have been highlighted. In order to facilitate the explore-PAS phase in case of large solution spaces, the support of genetic algorithms has been investigated and the exiting method ParaGen has been further implemented. Final case studies have focused on the potentials of ParaGen to identify well performing solutions; to extract knowledge during explore-PAS; and to allow interventions of the designer as an alternative to generations driven solely by coded criteria. Both the use of PAS and its recommended future developments are addressed in the thesis.
