Behavior of Plank (Tongue and Groove) Wood Decking under Uniformly Distributed Loads
Publication: Journal of Performance of Constructed Facilities
Volume 29, Issue 4
Abstract
An experimental program was undertaken at the University of Ottawa’s structural laboratory to investigate the behavior of plank decking under uniformly distributed loads. Nondestructive and destructive tests were conducted on plank decking systems to investigate their stiffness and failure mode characteristics. The study showed that the established deflection coefficients used to check the deflection of plank decking under balanced uniformly distributed loads can be conservatively used to estimate the stiffness of the simple span, two-span continuous, and controlled random layup patterns. It was also found that a deflection coefficient of 0.60 would be suitable for the combination simple and two-span continuous layup. Under unbalanced loading on two-span continuous layups, it was found that the deflection coefficient of 0.42 was nonconservative and that a more appropriate value to use in this case would be 0.60. The failure mode of a controlled random layup decking system under a uniformly distributed load was found to be consistent with the failure observed for simple span. The assumption of basing the capacity of the controlled random layup on the capacity of simple span layup seems appropriate.
