IASS 2019The International Conference FORM and FORCE 2019 will be organised on 7-10 October 2019 in Barcelona, Spain.

FORM and FORCE 2019 incorporates:

  • the IASS 60th Anniversary Symposium (IASS SYMPOSIUM 2019) and
  • the 8th International Conference on Textile Composites and Inflatable Structures (STRUCTURAL MEMBRANES 2019)

Following the customary celebration of the IASS Symposium every ten years in Spain and the Structural Membranes Conference every four years in Barcelona, the organizers have found an outstanding opportunity to merge both communities into a joint international conference that aims to provide a forum for state-of-the-art contributions and fruitful discussion in the broad fields of shell, spatial, tension and inflatable structures.

FORM and FORCE 2019 will be held at a modern hotel in downtown Barcelona with very good connections to the airport and the city centre. An attractive combined accommodation-registration package will be offered to all participants.

The city of Barcelona offers a privileged canvas for this joint scientific-technical meeting, as it gathers a large number of outstanding historical and contemporary spatial structures, as well as world-class cultural and recreational attractions.

The conference will cover all aspects related to material, design, computation, construction, maintenance, history, environmental impact and sustainability of shell, spatial, tension and inflatable structures in all fields of application.

The conference topics will include (the list is not exhaustive):

  • Conceptual Design
  • Shell Structures
  • Computational Form Finding
  • Tension and Membrane Structures
  • Optimization
  • Inflatable Structures
  • Computational Methods for Analysis
  • Framed and Lattice Structures
  • Detailing and Construction
  • Gridshells and Bending-Active Structures
  • Testing Procedures
  • Tensegrity Systems
  • Maintenance Techniques
  • Adaptive Systems
  • Advanced Manufacturing
  • Deployable and Origami Systems
  • Advanced and Bio-based Materials
  • Temporary Structures
  • Environmental Compatibility
  • Metal Spatial Structures
  • Historical Structures
  • Timber and Bio-based Structures
  • Teaching and Education
  • Glass Structures
  • Applications: shell roofs, shell structures for power technology, masts and towers, tile vaults, membrane roofs and covers, sails, inflatable pavilions and buildings, light-weight bridges, airships and airspace structures, inflatable antennas, high altitude platforms, furniture, bio-medicine, textiles for clothes, etc.

In addition to incorporating the Annual Symposium of the International Association for Shell and Spatial Structures (IASS), FORM and FORCE 2019 will be proposed as a Thematic Conference of the European Community on Computational Methods in Applied Sciences (ECCOMAS) and a Special Interest Conference of the International Association for Computational Mechanics (IACM).

Competition and exhibition of innovative lightweight structures
Working Group 21 is organising a competition for innovative pavilions at the 2019 IASS Symposium. Full details, and application form for groups can be found here:
