Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors. (2012)
Presentation / Conference Contribution
Khokhar, A., Chui, Y., & Smith, I. (2012, July). Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors. Presented at World Conference on Timber Engineering

Floors with repetitive parallel wood joists overlain by wood panel sheathing behave as orthotropic two-way structures since their along-joist stiffness is much higher than across-joist stiffness. Due to this orthotropy, they have a tendency to produc... Read More about Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors..
