This research addresses the vibration performance of mass timber floors, which is crucial for their structural design and maximum allowable span. As mass timber construction is relatively new, there is a lack of specific design
guidance, especially for floors with beam supports and concrete toppings. Our goal is to assess the vibration serviceability of a large-scale mass timber floor with glulam beam supports using vibration testing and subjective
evaluation. The outcomes will provide valuable data for the industry partner to support the design of vibrationresistant mass timber floors.
