Integral Mechanical Attachment for Timber Plate Structures (IMA)

The collaborative research project Integral Mechanical Attachment for Timber Plate Structures explores new structural typologies built from timber plates to find out how traditional fastening techniques for timber plates can be replaced by or optimised with integral attachment. The innovative technique developed during this project would allow for a rapid and precise on-site assembly, making the of use of additional metal connectors redundant. Questions of geometry, fabrication data and code generation, prefabrication and on-site assembly, structural analysis and understanding of the proposed details and overall structures are essential for the application of this construction technique to buildings. The proposed design, analysis and fabrication methods are heavily based on computation strategies. Therefore, the project is developed in close collaboration not only between researchers from the fields of architecture, structural engineering and computer graphics and geometry.
