| Research Abstract |
The effect of the moisture on the creep fracture and the duration of load factor of lumbers and particle boards were clarified through the test results of the long term loading tests on these two materials. The long term loading test was conducted in two different climates, the climate of the standard condition and the dry and humid cyclic climate. Common to the two materials larger deformation was observed for the test specimens loaded in the dry and humid cyclic climate. And the test specimens loaded in the dry and humid cyclic climate showed smaller duration of load factor.
