Abstract
The present paper investigates possible impacts of the climate change on building
risks caused by typhoons. The inputs to this investigation are: (1) outcomes from the numerical
simulations with a Global Climate Model (GCM) developed under the framework of the KAKUSHIN
program, (2) statistics on building damage in the event of Typhoon Songda, and (3)
numerical simulation of the wind field induced by the typhoon Songda with the JMA Non-
Hydrostatic Model (JMA-NHM). The first input is utilized to develop two sets of probabilistic
typhoon models; i.e. corresponding to the current climate and the future climate subject to the
climate change, whereas the other inputs are utilized to develop a model for structural performance
of buildings. Taking basis in these models, changes of building risks under the climate
change are investigated. The result shows that the building risks slightly decrease in most of the
regions in Japan, due to the decrease of the frequency of typhoon events, in spite of the increase
of the frequency of intensified typhoon events.
