international association for shell and spatial structures



Working Group 15: Structural Morphology

Mission

Innovation of building structures through research on form, material and fabrication.

Background

Since its founding in 1991, the "Structural Morphology Group" (SMG) has focused on the relationship between geometry and structures.  Over the years, the working group has published 15 SMG Newsletters, organized 7 international seminars, and held numerous special sessions at the annual IASS symposia, culminating in the publication of “An Anthology of Structural Morphology” in 2009.  A sub-working group on Free Form Design was established in 2005 and organized 2 international seminars.  In 2009 after the 6th international seminar of the SMG “Morphogensis,” the sub-working group was merged to form an integral part of the working group.

The working group supports the formation of ad hoc study groups that focus on specific topics around its research interest and stimulates researchers from inside and outside the SMG to participate in these study groups.  The study groups provide a platform for researchers, engineers and designers to communicate and share knowledge in the various research fields linked to structural morphology.  Members of the SMG and IASS are encouraged to contribute to the study groups by performing research, publishing articles related to the research fields, informing other members of interesting activities worldwide, discussing new niches in research and other activities aimed at knowledge sharing and dissemination.

Current Objectives

  1. To propose a special issue of the Journal of the IASS on "Structural Morphology".
  2. To develop a web-based archive of timber spatial structures and timber technology on the WG12 area of the IASS website
  3. To publish a state-of-the-art report on the structural design and architecture of timber spatial structures.
  4. To expand the membership of the group interested in timber grids (single layer, double layer, reciprocal frame, lamella); shells; grid shells; domes and vaults; bridges; innovative timber-based materials; engineered timber; joints; bamboo structures; historic and high-rise timber structures.

Research Foci

  • Geometry: describing and controlling (complex) geometry, including parametric design
  • Form-Force relationship: the study of the interdependency of structural geometry and mechanical or kinetic behaviour
  • Form-Mobility relationship: the study of the interdependency of structural geometry and transformability
  • Computation: design, calculation, performance, form finding, optimisation, morphogenesis, parametric design, etc.
  • Technology transfer: cross over with other disciplines, e.g., mathematics, biology, etc.
  • Prototyping: physical and virtual model making and fabrication

Current Objectives

  • Organize special sessions at IASS Symposia and Colloquia related to Structural Morphology
  • Organize every three years an international seminar to present and discuss the results of the SMG study groups
  • Publish state-of-the-art reports on the research done by the SMG study groups
  • Contribute to the organization and editing of Special Issues of the Journal of the IASS related to Structural Morphology and the SMG study groups

Current Study Groups

Transformable Structures (study group leader: Niels De Temmerman): The research objective of the study group Transformable Structures is to bring together expertise and expand knowledge related to the geometric design and structural analysis of transformable structures within the field of architectural and structural engineering. The transformation of such structures, aimed at adapting to changing circumstances, is either done by mechanisms (deployable/foldable) or through the use of reconfigurable components (dismountable/meccano-like).

Origami (study group leader: Tomohiro Tachi): The research objective of the study group Origami is to bring new ideas, based on origami research, to the field of structural design and fabrication technologies. The goal of the study group goes well beyond the application of origami patterns in design. The aim is to innovate structures and fabrication technologies through the fundamental understanding of the dynamic and geometric characteristics of origami.

Active Bending (study group leaders: Christoph Gengnagel and Julian Lienhard): The primary goal of the 'Active Bending' study group is to support a focused exchange for engineering researchers and practitioners that share exploiting elastic bending as a means to generate curved geometries from initially straight or planar building elements.

Graphical Methods (Study group leader: Philippe Block and Corentin Fivet): The “Graphical Methods” study group’s aim is to discover lost knowledge and techniques, develop novel methods and tools, share practical case studies, and, in general, to educate architects and structural engineers of the power of graphical approaches in structural design and analysis, to promote their use. 

Activities during 2016-2017

  • Organised a number of special session(s) at the IASS Symposium 2016 in Tokyo, Japan; amongst others, one with a special emphasis on Origami and a Joint session of WG13 and WG15 on Active bending and flexible structures
  • Exhibition on 'Structural origami' Sept. 10th-Oct.2nd 2016: http://museum.c.u-tokyo.ac.jp/2016.html#origami2    
  • ReciPlyDome: a transformable reciprocal frame structure with bending-active elements, as part of an exhibition on circular building design at KADK Kopenhagen: http://www.vub.ac.be/ARCH/ae-lab/projects/reciplydome

Anticipated Future Activities

  • Organise special session(s) at the IASS Symposium 2018 in Boston, USA
  • Organise a Masterclass on Structural Morphology at IASS 2018
  • Publish a state-of-the-art report or paper
