Natural disasters have been creating catastrophic damage because of climate change associated with global warming. On the other hand, the social infrastructure constructed in the period of rapid economic growth is aging. Therefore, damage risk analysis and new construction/repair planning for the infrastructure are becoming important. The Research & Innovation Center of Mitsubishi Heavy Industries, Ltd. (MHI) has its own simulation technologies for various types of disasters such as floods, tsunamis, earthquakes, typhoons, fires and leakage/explosions(1) and has analyzed risks associated with climate change and developed countermeasure devices intended to improve infrastructure resilience (strength and recovery capability). In this report, focusing on typhoons, which are disasters familiar to us as they occur frequently, we introduce the outline of the typhoon damage simulation technology among MHI's simulation technologies, simulation examples including the risk analysis for roof uplift damage and strong wind damage, the development of damage reduction devices and the design wind velocity maps which visualize typhoon damage risk.
