Characteristics of seismic activity before and after the 2018 M6.7 Hokkaido Eastern Iburi earthquake
Earth, Planets and Space, 2019 We applied the epidemic type aftershock sequence (ETAS) model, the two-stage ETAS model and the non-stationary ETAS model to investigate the detailed features of the series of earthquake occurrences before and after the M6.7 Hokkaido Eastern Iburi ...

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Structural Concrete, EarlyView.Abstract Accurate estimation of the damping ratio is critical for evaluating floor response spectra and equipment seismic demands in nuclear power plant structures. This study investigates the elastic damping ratio of reinforced concrete walls under limited damage states through shaking table tests and data‐driven modeling.
