This volume collects the latest advances, innovations, and applications in the field of shell and spatial structures, as presented by leading international researchers at the 2nd Italian Workshop on Shell and Spatial Structures (IWSS), held in Turin, Italy on June 26-28, 2023. The conference was meant to give an overview on experimental and theoretical studies, analysis methods and approaches for the design, computational form finding, structural optimization, manufacturing, testing and maintenance techniques and historical reviews of all types of shell and spatial structures. These include, but are not limited to, tension and membrane structures, framed and lattice structures, gridshells and active-bending structures, shell roofs, tensegrity structures, pneumatic and inflatable structures, active and deployable structures, concrete, metal, masonry, timber and bio-based, spatial structures. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.
