international association for shell and spatial structures


WELCOME TO THE IASS

– an association that gathers engineers, architects, builders and all others interested in lightweight structural systems such as lattice, tension, membrane, and shell structures, and more broadly interested in the creative integration of structural engineering and architecture.

Why Shell and Spatial Structures?

The continual development of lightweight structural systems has made it possible for structures to carry a far greater load than their self weight. Shells and spatial structures are on the very front of this breakthrough in efficient use of materials.

The continuing development of design, analysis, and construction techniques of shell and spatial structures has resulted in an increasing fund of information of practical interest to architects, engineers, and builders. The IASS, founded by Eduardo Torroja in 1959, has as its goal the achievement of progress through an interchange of ideas among all those interested in lightweight structural systems.
