Abstract

It is known that the wind damage spreading of residential houses is more strongly affected by gust speeds rather than maximum wind speeds. Furthermore, the age and the structure of buildings influence outbreaks of wind damage. The authors proposed the method to estimate residential damage rate associated with typhoon by considering wind-resistant performance of houses and strong winds. The residential damage rate has been better estimated using modified wind speeds associated with building structure distributions in municipalities. Residential damage rate due to strong winds might be able to estimate better considering performances of houses such as roof form, exterior material and maintenance. Considerable affecters to estimate residential damage rate more correctly should be established.
