IASS-IWSS 2026: IASS 2026 Symposium - IWSS 2026 joint conference, R-Evolution of Shapes: Sustainability, Re-Use, and New Design Paradigms OGR Officine Grandi Riparazioni - Politecnico di Torino Torino, Italy, September 14-18, 2026

The IASS–IWSS 2026 joint conference, to be held in Turin, Italy, in September 2026, will bring together experts, researchers, and professionals from around the world to share research, experiences, and cutting-edge developments in the field of shell and spatial structures.

The event is jointly organised by the International Association for Shell and Spatial Structures (IASS), a long-standing international reference on lightweight structural systems, and the Italian Association for Studies on Shell and Spatial Structures (4S Association), which promotes Italy’s heritage  and research in the field. The IASS organizes annual International Symposia on themes related to lightweight long-span structures of interest to engineers, architects and builders. The 4S Association is  responsible for the Italian Workshop on Shell and Spatial Structures (IWSS), a triennial meeting whose previous editions were held in 2020 and 2023.

The IASS–IWSS 2026 therefore represents a unique opportunity to actively contribute to scientific and professional discussions on frontier topics in structural and architectural innovation, fostering interdisciplinary dialogue between research, design, and construction practice.
