Fundamental Research on Tsunami-Resistant Design for Coastal Architectures Considering Hazard Chains

In this paper, the most important research issues for tsunami-resistant planning and design of coastal buildings located in port cities are as follows: (1) from the initial event to the result event, that is, considering the hazard chain establishment of a design process that. (2) At the same time, considering that tsunami disasters are sudden, low-frequency catastrophes that are characteristic of tsunami disasters, the development of simulation methods that consider the hazard chain is also an extremely important issue. (3) To clarify the characteristics of the tsunami impact load caused by the tsunami run-up with drifting objects and at the same time to develop a practical numerical analysis method that can predict the impact load rationally and quantitatively. As mentioned above, this paper summarizes some of the results of the research conducted for the above-mentioned three subjects.
