International Association for Shell and Spatial Structures

The International Association for Shell and Spatial Structures (IASS) is a global professional organization dedicated to advancing knowledge and collaboration in the design, analysis, and construction of lightweight, flexible, and innovative structures like shells, grids, and spatial frameworks. These structures often feature curved, thin surfaces that are both aesthetically striking and structurally efficient. IASS brings together engineers, architects, and researchers to share research, develop new techniques, and promote best practices in creating these complex forms, which are used in stadiums, roofs, and architectural marvels around the world.
