Seismic response prediction for nonlinear isolation bridges using output only
November 2025 • Hiroto Yamada, Xinhao He, Shigeki Unjoh, Yuguang Fu
Abstract In earthquake-prone regions, the rapid post-earthquake evaluation of numerous bridges poses a significant challenge, further exacerbated by infrastructure aging. While monitoring technologies are actively being developed to address this issue, sensor placement and measurement selection remain critical obstacles, as bridges often feature unique design conditions that require generalized analysis methods and exhibit strong nonlinear behavior during earthquakes. Such behavior restricts the applicability of m…
