Earthquake Lifeline Engineering Lab
Machine-translated · View original
The lab analyzes how structures are damaged in earthquakes and works to reduce that damage.
AboutAbout the lab
Minimizing earthquake damage to structures.
The Earthquake Lifeline Engineering Lab conducts research to reduce earthquake damage to structures.
Targeting lifelines, bridges, historic buildings, and more, it reproduces their behavior during earthquakes by combining vibration measurement, numerical analysis, and experiments.
It investigates structures damaged in earthquakes in Japan and overseas, identifies why they failed, and proposes countermeasures for the future.
It also pursues research on structural health monitoring, which evaluates the degree of damage to a structure from how it vibrates.
Key terms
- Lifeline
- Facilities essential to supporting daily life, such as roads, railways, water supply and sewerage, gas, electricity, and telecommunications
- Structural health monitoring
- A technology that measures how a bridge or building vibrates and examines the degree of deterioration or damage from changes in that vibration
- Restoration to the original form
- Returning a cultural property building to its original form when repairing it, so as not to compromise its value
ResearchResearch themes
The lab develops numerical analysis methods that can reproduce in 3D how structures move and fail during earthquakes, from the elastic range through to collapse. It also works on theories and tools for evaluating the soundness of structures from vibration measurements.
*Illustrative imageMaking Lifeline Facilities Earthquake-Resistant
The lab studies technologies that keep lifeline facilities such as roads, railways, water supply and sewerage, gas, electricity, and telecommunications functioning during earthquakes. It checks mainly through numerical analysis whether new structural forms are effective.
*Illustrative imageProtecting Historic Buildings from Earthquakes
The lab develops analysis methods that reproduce in 3D how structures fail, and uses them to examine the seismic safety of historic buildings and the mechanisms of earthquake damage. Even for cultural properties, where restoration to the original form is the principle, it considers measures that improve seismic performance without compromising their value.
*Illustrative imageEvaluating Structural Damage from Shaking
Structures are damaged by earthquakes, and small damage also accumulates through aging year after year. The lab builds the theory of methods that measure structural vibration and evaluate soundness from its characteristics, and improves their accuracy by verifying them with experiments and observations.
*Illustrative imagePredicting Earthquake Shaking with Deep Learning
Mainly for bridges, the lab builds models that predict shaking during earthquakes by applying deep learning to accumulated observation data. It develops methods that make visible the frequency features that contributed to a prediction, achieving both accuracy and explainability.
