Host Researcher |
Takashi FURUMURA |
During my stay at ERI, I will work with Prof. Furumura on improving the
engineering assessment of earthquake ground motions in sedimentary basins,
where many major cities facing high seismic hazard (e.g. Los Angeles, Tokyo
and Mexico City) and much critical infrastructure are located. Currently,
earthquake ground motions in sedimentary basins are poorly assessed, particularly
for structures with long natural periods (e.g. high-rise buildings, nuclear
cooling pools and towers, long-span bridges). This is because while the
standard assessment approach assumes that near-surface soil layers respond
in a one-dimensional manner, sedimentary basins do not fulfil this assumption.
In this project, we will use improved understanding of earthquake ground
motions obtained by simulations and observations to develop and disseminate
a robust and practical methodology to improve the current engineering practice
in seismic hazard analysis within sedimentary basins.
