The mission of the WG on "Historical Spatial Structures" is the documentation and preservation of the built heritage of the modern era for future generations.
The current objective of WG17 is to raise awareness and develop identification, rehabilitation and restoration strategies for the 20th C. Heritage of Spatial Structures.
As one step toward meeting this objective, WG17 organizes special sessions in IASS Symposia. In addition, documentation on reinforced-concrete shell and folded-plate structures in various countries has been started. Later, other types of spatial structures may be considered.
All current members of the Working Group, listed below, are members of the IASS. The Working Group welcomes additional members; those interested should please contact the Chair of the Working Group.
