It is necessary to estimate stress concentration by using the biased distribution of roof snow to obtain an earthquake resistance assessment of timber structure houses in snowy season, because the roof snow glides due to vibration and it vibrates separately from the house structure. A primary vibration test was performed in this study for the purpose of collecting the basic data to estimate earthquake resistance of timber structure houses in snowy region. As a result, it became clear that 1) The response acceleration of the models when the snow broke and glided was 0.5 to 0.9 times that observed before gliding; 2) The response acceleration of the model after the snow glided was affected by the surface roughness. When the roofing material had greater surface roughness, the snow glided irregularly, and the response of the models increased; 3) In this study, the fluorine-coated steel sheet (Rz=4.20μm) was associated with the largest decrease in the response acceleration of the model.
