Vibration Testing of CLT Floors


Oregon State University

Led by Oregon State University, this research project examines Albina Yard as a case study to better understand the vibration that occurs in mass timber buildings. Low levels of vibration are present in all types of multi-story buildings, and the ability to keep vibration below acceptable limits is critical to occupant comfort and building performance.

This study focuses on vibration caused by footfall traffic, mechanical equipment, or outside sources such as vehicular traffic and wind. Using an array of accelerometers placed throughout the building, the project team is currently collecting vibration data during typical building operation. The data collected at Albina Yard will be analyzed against modeled vibration predictions for mass timber structures. This research project is providing valuable performance data that is relevant as mass timber becomes more widely adopted in mid- and high-rise construction.
