As the damages due to natural disasters continue to increase, a growing interest is being witnessed in such studies that focus on preventive measures to reduce damages rather than on their recovery. As such, the U.S. has been actively conducting projects to develop new models that can forecast potential damages due to natural disasters and widely employing them in actual cases. With no specific models developed in Korea yet, this study aimed to introduce an overseas typhoon model as part of the advanced efforts and apply it the actual cases occurring across the nation. This model estimates wind loads by measuring the impact of a strong wind upon buildings, and measurements require a number of parameters. Those parameters should include the types and dimensions of buildings and the type of the roofs. As for the FPHLM(Florida Public Hurricane Loss Model), a precedent model for our study, we were able to take advantage of number of the statistics and detailed categorizations on the residential buildings in the U.S., which enabled us to select the representative building types and produce their wind loads. With no sufficient relevant statistics available for the nation, however, we may not be able to readily measure the wind loads on the nation’s residential buildings. Therefore, this study tried to choose the representative types, heights and dimensions of the buildings for the measurement of wind loads. We consequently came up with a representative house having an area between 62.81 and 95.56 ㎡, either a flat roof or hip roof, a height of 2.6 m, an side ratio of 1.5, and the width and length of the mean 85 ㎡ sized house being 11,300 mm and 7,530 mm, respectively.
