Towards Reliable Vibration Design of Mass-Timber and Timber-Concrete Floors: Data, Models, and Practical Guidance

The proposed project studies the vibration behaviour of innovative mass timber floor systems, focusing on cross-laminated timber (CLT) floors supported by CLT beams and timber-concrete composite (TCC) floors with notched connections. Using laboratory testing and numerical modelling, the research aims to enhance the understanding of how these floors respond to dynamic loads, including the effects of non-structural components such as concrete toppings, which can add mass and damping. The project will generate validated experimental data and finite element models to develop design guidelines that improve vibration serviceability, occupant comfort, and structural performance. Collaboration between Canadian and Italian institutions strengthens the research by combining expertise and access to advanced facilities. The project aligns with Canadian CSA O86 standards and European Eurocode 5 design provisions, helping harmonize approaches to timber floor vibration across North America and Europe. This collaboration supports the advancement of mass timber design standards, expanding market acceptance of innovative floor systems and enhancing the capacity of participating institutions to address vibration challenges in sustainable construction. Through joint supervision, knowledge exchange, and shared resources, the project aims to establish international partnerships and contribute to safer, more efficient timber buildings.
