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).


The theme of the IASS 2023 symposium was Integration of Design and Fabrication, which is becoming increasingly important with the developments of digital technologies in both design and manufacturing. The symposium covers all aspects related to material, design, computation, construction, maintenance, history, environmental impact and sustainability of shell and spatial structures in all fields of application.

The symposium was held at Melbourne, from 10th till 14th July.
