Working Group 17: Historical Spatial Structures


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.

Current Objectives

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.
