Encourage the development of computational aspects appearing in the different phases of creation, design, construction and maintenance of shell and spatial structures.
History and Background
IASS Working Group No. 13 was founded in 1984 at the Dortmund Annual IASS Symposium under the leadership of Prof. Avelino Samartín. The original name of the WG was Numerical Methods in Shell and Spatial Structures, but this has since been generalized to accommodate all types of computational approaches. Therefore, the group interacts with the activities of other IASS Working Groups and aims to support them on their specific tasks.
Over the years, a principal activity of the WG has been to organize International Colloquia. The first three of these were held in Leuven, Belgium in 1986; Tokyo, Japan in 1993; and Taipei, Taiwan in 1997. Subsequently, they have been organized jointly with the International Association for Computational Mechanics (IACM), and these IASS-IACM Conferences have been held in Chania, Crete in 2000; Salzburg, Austria in 2005; Ithaca, New York, USA in 2008; and Sarajevo, Bosnia-Herzegovina in 2012.
A Sub-Working Group on Computational Morphogenesis was established in 2003 at the IASS Symposium held at Montpellier, France, as a part of this WG. The Sub-Working Group, led by Prof. Hiroshi Ohmori, organized the IWCM2006 (International Workshop on Computational Morphogenesis) at Nagoya, Japan to diffuse thoughts on how computational morphogenesis can contribute to the art of structural design and to exchange ideas on utilization of structural optimization for structural design. Subsequently, the sub-group was merged as one of the integral parts of WG13 and Prof. Ohmori became co-chair of the WG.
In the period between 2009 and 2012, Profs. Samartín and Ohmori stepped down as chairs, and the leadership of the group moved to the current co-chairs.
The creation of a study group on Next Generation Parametric Design reflects the aim to include aspects of computation with increasing relevance in the creation and design of shell and spatial structures, as: Parametric Modelling, Generative Design, Data Visualization and Integration, Machine Learning, AI Approaches.
