Integral Mechanical Attachment for Timber Plate Structures (IMA)

Our main goal is to provide a new construction system made out of timber plates without using additional connectors, such as screws, nails and glue. In addition to code generation for fabrication data purposes and geometrical studies, including optimising the form, the project intends to take the structural mechanics of integral mechanical attachment into account. Researchers from computer science, architecture and structural engineering come together to provide an integrated framework to develop new structural typologies. Within the framework, we investigate the typology of the system, optimised geometry of integrally-attached timber plates, fabrication and assembly constraints, application of timber-to-timber multiple-tab-and-slot connections and their constraint in large-scale structures, structural serviceability, structural mechanics, and practical-oriented computational model development.
