In regions with heavy snowfall, such as Akita, the primary load on the structural design of school gymnasiums is the snow load. However, for recording heavy snowfall, the regional distribution of the snow load is modified. As a result, the amount of snow load to be considered in the seismic diagnosis of gymnasiums is not clear. Occasionally, these gymnasiums are unable resist the long-term load during heavy snowfall.
In this study, the annual transition of the snow load on a structural design was investigated using the past records for a prefecture and a self-governing body.
