Point-supported flat slabs are structural floors commonly used in buildings to withstand vertical loads and distribute them directly to columns without the use of beams. Mass timber floor panels have been recently presented as an alternative to concrete slabs. However, point-supported floors typically behave as two-way slabs and are most often constructed using reinforced or post-tensioned concrete, and there is little data available on point-supported mass timber floor slabs and their two-way behavior. This paper develops insights into the dynamic behavior of point-supported mass timber panels through an experimental evaluation of 12 specimens, including three 5-ply cross-laminated timber (CLT) panels, three 7-ply CLT panels, three 5-ply mass ply panels (MPPs), and three 6-ply MPPs. The panels were supported on six (6) columns, with a column grid of 2 × 4.88 m by 3.05 m and 2 × 4.88 m by 3.66 m for the CLT and MPP specimens, respectively. The experiments tested and measured human-induced vibrations based on heel drops and walking in a line at different footfall rates per minute. Vibrations were measured using 13 uniaxial accelerometers oriented in the vertical direction. This paper presents the application of conventional output-only methods, such as Enhanced Frequency Domain Decomposition (EFDD) and Stochastic Subspace Identification (SSI), for modal analysis of point-supported mass timber slabs. The results provide insights into the dynamic behavior of point-supported CLT and MPP slabs, providing data for developing advanced finite element models and confidence in human-induced floor vibration designs.
