Abstract: The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the behavior of wood beams throughout a reference time period is analyzed and evaluated for a limit state corresponding to maximum midspan deflection. A resistance factor for use in an LRFD format is suggested.
