The purpose of this study is to clarify the influence of over-driven of nail to shear strength of structural wooden panels. It is said that the over-driven of nail decrease shear strength, however, there is no enough data about this problem. Therefore we conducted single shear tests on OSB nailed joints and static loading test of SIP shear walls. The following main results obtained by this study are: 1) Over-driven of nail decrease shear strength, though the decreasing rate is lower than structural plywood. 2) There is little influence of over-driven of nail to SIP shear walls.
