Summary
With the rapid development of CLT manufacturing capacity around the world and the increasing architectural acceptance and adoption, there is a current and pressing need regarding adhesive bond quality assurance in manufacturing. As with other engineered glued composites, adhesive bondline performance is critically important. Bondline assessment requires technology in the form of sensors, ultrasonics, load cells, or other means of reliable machine evaluation. The objectives of this cooperative study are to develop quality assurance procedures for monitoring the quality of mass timber and CLT during and after manufacturing and to develop assessment techniques for CLT panels in-service.

Notes
Building on the results of an earlier project that established protocols for post-occupancy building monitoring, this project aims to install a system in the new Peavy Hall building at Oregon State University to monitor moisture, relative humidity, vertical and slip movements due to shrinkage & deflection, post-tensioning losses, vibration and seismic activity. The monitoring system will establish a “living” laboratory that demonstrates in real time how the mass timber components of the building are affected by various internal and external phenomena. The data will be gathered and analyzed over the service life of the building.
