Work is reported which developed an experimentally verfied theoretical model based on the data from constant-load tests for predicting creep slip of nailed joints under variable loads. The models are based on existing creep formulations for nonwood materials and mechanisms of load transfer between nails and wood. They accounted for instantaneous and delayed elastic, plastic, and viscous-viscoelastic behavior, and incorporated the modified superposition principle (MSP) and the strain-hardening principles. Fourier series approximation was also included to describe discrete stepwise loading as continuous functions. Constant-load tests were conducted to develop specific models for nailed joints between wood framing members and plywood sheathing. The results from stepwise load tests on the same type of joints provided the data for assessing the accuracy of these models.
