The International Association for Shell and Spatial structures (IASS), founded by Eduardo Torroja in 1959, has as its goal the achievement of further progress through an interchange of ideas among all those interested in lightweight structural systems such as lattice, tension, membrane, and shell structures.
IASS organises annual it International Symposium on themes of general interest to engineers, architects and builders.
The Working Group 6 on Tension and Membrane Structures is chaired by Ken'ichi Kawaguchi (Chair) and Marijke Mollaert (Co-Chair).


Innovation, Sustainability and Legacy conference, will be organised by the Beijing University of Technology, China Association for Spatial Structures and China Steel Construction Society in Beijing, China, on 19 – 23 September 2022.
