Abstract: The adequacy of the duration of load factor was discussed in terms of the accuracy of the stress level. The results are summarized as follows: (1)The duration of load factor will be not be conservatively evaluated when the samples being tested have a wide variety in their bending capacity. (2)When the distribution of the bending capacity of the samples has smaller coefficient of variation the load bearing capacity of the each samples can be more accurately estimated. And as a result the duration of load factor can be adequately evaluated. (3)An alternative testing and evaluation method to evaluate the duration of load factor of the structural wooden materials was proposed. The method was based on the ides that the test specimens that do not fail for a long time should have higher bending capacity than the test specimens that fail in a short period. And the stress ratio was adjusted on this idea. The duration of load factor was well evaluated by the proposed alternative testing and evaluation method.
