| Abstract |
In earthquake-prone areas, the risk of flooding has increased due to rapid climate change. Therefore, buildings in these areas need to mitigate not only earthquake risks but also flood risks. One solution is to use floatable buildings. This study presents a basic examination of the seismic performance of these floatable buildings by proposing an analytical model and comparing it with experimental results. In the experiments, models were placed in a water basin and subjected to impact and earthquake loads using a one-directional shaking table. Comparing the experimental results with the analysis, it was found that the friction-displacement model and the Housner model could effectively analyze floatable models. The analytical results showed good correspondence with the experimental results in determining the maximum building acceleration response. |
