| Research Abstract |
There is a possibility that the decrease of structural performance by the progress of the deterioration happen while the timber structure's being used in a long time. In this research, an experimental research concerning the deterioration by moisture was conducted for the panel sheathed shear wall and its nailed joint. The result is as follows. The performance persistence ratio is different depending on the kind of the wood-based structural panels. The performance persistence ratio changes depending on the deterioration and the test method. It is necessary to propose a more accurate test and evaluation method, because of insufficiency of present evaluation method.
