Working Group 12: Timber and Bio-Based Spatial Structures

Mission

To disseminate state-of-the-art information on the structural design and architecture of timber spatial structures and promote their use as an environmentally benign form of construction.

Background

The Working Group has been developing the approach to bio-based materials in spatial structures, which is reflected in the changes of names of the working group, from Spatial Wood Structures, through Timber Spatial Structures to the current name Timber- and Bio-based Spatial Structures. The interests and activities of its members form the working group profile and the field covered today spans from timber gridshells, plate based timber structures, bamboo and paper structures to bio-inspired concepts in form-finding and material science. The Working group attracts both engineers and architects studying the use, development and innovation of timber- and bio-based materials and concepts in conception, design and production of spatial structures.

Current Objectives

  1. To guest-edit the special issue of the Journal of the IASS in 2023 on "Timber and Bio-based Spatial Structures."
  2. To develop a web-based archive of timber spatial structures and timber technology on the WG12 area of the IASS website
  3. To publish a state-of-the-art report on the structural design and architecture of timber spatial structures.
  4. To expand the membership of the group interested in timber grids (single layer, double layer, reciprocal frame, lamella); shells; grid shells; domes and vaults; bridges; innovative timber-based materials; engineered timber; joints; bamboo structures; historic and high-rise timber structures.
