Snow risk management for a building in snowy regions

作者将雪害问题定义为建筑物在每年一度的重大活动中的雪害风险，是一种罕见的降雪灾害。本研究的目的是系统化的雪风险管理组成的风险评估，通过使用量化的雪风险的基础上的建筑物上的雪损害的概率。本研究以问卷调查方式，探讨强降雪地区雪害问题之特性。特别是在北海道，地面积雪问题和由飘雪引起的建筑物可能存在很大的风险。对雪害进行了判别分析，并利用损失期望值进行了风险评估。提出了建筑物积雪风险管理的流程图。

The author defines snow problem as snow risk on building at an annual event and a rare disaster with snowfalls. The aim of this study is to systematize snow risk management composed of a risk evaluation by using the quantification snow risk based on the probability of snow damage on the buildings. In this study, characteristics of snow problems in heavy snowfall regions were obtained by a questionnaire survey. Especially, in Hokkaido, snow problems on the ground and caused by drifting snow could be a great risk of the building. Discriminant analysis for causing snow damage was examined and the risk evaluation by using loss expectation also was conducted. The flow diagram of snow risk management for a building has been proposed.
