Abstract
Biological durability remains an understudied area of mass timber construction, despite expert warnings on potential moisture and decay issues that may affect building performance. In an effort to bridge the knowledge gap, this article presents experimental data on the performance of fungaldecayed cross laminated timber (CLT) connection assemblies. A total of 560 connection assemblies were made using select CLT species from major global markets. These were mechanically tested following inoculation by two brown rot fungi for a total period of 78 weeks, with the connections periodically harvested after 10, 20, 30, 40, 52, and 78 weeks. The data from the mechanical tests, which included cyclic evaluation using an abbreviated CUREE loading protocol and dowel bearing strength tests performed in accordance with ASTM D5764, are submitted in this repository. The repository also contains information on mass changes to connection assemblies as decay progressed and SAWS model parameters that were calibrated using the raw data generated from the universal testing machine (UTM) during cyclic tests of the connection assemblies. This work is fundamental for accurate assessment of fungal deterioration in mass timber buildings and the data submitted herein could be used by researchers and scientists to model behavior of connections in mass timber buildings, especially in humid and damp regions with high chances of biodeterioration.
