Description

It is essential for disaster prevention to quantitatively evaluate the earthquake vulnerability of urban infrastructures considering the duration of infrastructures in service, external loads to act on structure during earthquakes, cost of damage and restoration, and the cost of maintenance and retrofitting. For this purpose, we propose an integrated methodology that covers the prediction of strong ground motions for scenario earthquakes, control of structural damage of RC and steel building structures and evaluation of residual seismic performance after damage, and estimation of life cycle cost-based maintenance strategies.
