Identification of regional characteristics associated with extent of wind damage using a data-mining technique

由于风速、屋面形状等复杂影响因素的影响，结构的强风损伤不断扩大。然而，除了风速以外的大多数因素都没有具体说明。另一方面，像屋顶形式这样的结构条件与地区气候有关，例如积雪的数量。因此，考虑到屋面的结构状况与区域气候的关系，我们试图改进房屋的风灾评估程序。事实证明，冬季气候与屋顶形式有关，屋顶形式会影响房屋受损的程度。利用影响因素对损伤率进行了估计，并验证了估计的准确性。

The strong wind damage to structure is extended resulting from complicated influencing factors of wind speeds, roof forms and so on. However, most of factors other than wind speeds are not specified. On the other hand, structural conditions like roof forms are linked with regional climate, for example amount of snow cover. Therefore, we tried to improve the procedure of estimating wind damage to houses considering structural condition of roofs associated with regional climate. It turned out that winter climates are associated with roof forms and the roof forms affect on the extent of damage to houses. We estimated damage rate using the influencing factors and confirmed the estimation accuracy.
