The structural dynamic non-probabilistic reliability under the interval variable of loads changing over time and the interval variable of structural strength degrading over time is studied. The formulas for the change interval of structural strength degradation and its mean value and deviation are shown. According to the stress-strength interference theory and the interval theory, the structural dynamic reliability prediction model are established under the structural strength degradation over time while the loads of the structure bearing are classified three cases loads: ladder type, constant amplitude alternating type and random changing over time type. Finally, three examples are used to illustrate that the structural dynamic reliability models are reasonable and feasible.

Key words: structural, dynamic, interval, non-probabilistic reliability
