Summary
Floor vibration performance could govern the allowable span of mass timber floors. The objectives of this project are: 1. to develop a mobile app to collect data from lab and field mass timber floors for acceleration-based performance criteria; 2. to investigate the dynamic properties of mass timber floors under different boundary conditions; 3. to adopt frequency equations to predict the fundamental frequencies of mass timber floors under different boundary conditions; 4. to develop numerical modeling strategies for predicting vibration response of mass timber floors under footfall excitations.
