INTERLOCKING TIMBER JOINTS
This work develops analytical and numeric models for the structural assessment of interlocking timber joints.
Historic timber structures feature timber joinery connections that use interlocking geometries rather than fasteners. While timber construction since has gradually favored metallic fasteners, the longevity of historic timber structures utilizing joinery connections demonstrates their feasibility in structural systems and potential to enable sustainable constructions. Advancements in digital fabrication imply the ability to revitalize these complex geometries in competition with conventional fasteners. However, characterization of the mechanical behavior of joinery connections remains to be calibrated across analytical, experimental, and numerical models, let alone systematized across different geometric variations. This research examines the calibration between analytical models and experimental tests for historic interlocking timber joints.
This research has been developed at the Structural Xploration Lab, EPFL in collaboration with ARUP San Francisco and MIT Digital Structures.
