Outline of Final Research Achievements

A platform for strong wind risk assessment of houses consisting of a meteorological typhoon module, a statistical typhoon module, a strong wind damage module and a wind resistant performance database was constructed on GIS. The strong wind hazard calculated by the meteorological typhoon module showed downscaling calculations are needed to improve the accuracy of wind speed prediction. Therefore, the downscaling calculation by using Large Eddy Simulation was developed and installed in the platform. Model parameters in the statistical typhoon module were optimized in comparison with the great numbers of simulated typhoon. We can evaluate the amount of damage by using the platform. The modules and the database were designed as interchangeable so as to be able to considered the change of society. A risk assessment of strong wind damage to houses in a real city during a passage of typhoon was calculated. We derived a simple method of predicting the strong wind damage to houses.
