In case of wind speed, we estimated wind speed at 300m level using 700hPa wind according to the research method by Franklin(2003), PHRLM(2003), and Vickery and Skerlj(2005). Then we calculated wind speed at 10m level using the estimated wind speed at 300m level, and finally, peak 3-second gust on surface. The case period is from 18LST August 31 to 03LST September 1, 2002, when the typhoon Rusa in 2002 was the most intense. Among disaster prediction models in the US, Wind Field Module of PHRLM in Florida was used for the 2002 typhoon Rusa case. As a result, peak 3-second gust on the surface increased 10~20% in the typhoon's 700hPa wind speed.
The number of flat roof and hip roof type housing is high in Korea, The ratio of width and length of a single housing is about 1.5 and the height of a floor and ceiling are 2.6`3.0 m and 2.3`2.6 m, respectively.
