This manuscript presents a fragility assessment to evaluate the effects of far-field
earthquakes on the damage of the AP1000 nuclear island building (NIB), by using …

Researches explicitly indicate that the seismic events, consisting of the several shock waves
(the first followed by the aftershock or train) may result in cumulative damage even if the …

The purpose of this study is to investigate the efficiency of various structural modeling
schemes for evaluating seismic performances and fragility of the reactor containment …

A steel pipe elbow is an important component in the piping system of a nuclear power plant.
Accordingly, its structural performance requires a piping system with high-structural integrity …

Alkali silica reaction (ASR) is a nefarious one that has been observed in many dams. Its
recent discovery in a nuclear containment vessel structure (NCVS) in the US has taken the …

Historically, the dynamic testing of concrete dams has been associated with experimental
modal analysis (EMA) and the performance of forced vibrations tests. Nevertheless, this type …

Recent disruptive events, such as earthquakes or floods, have caused severe damage to
civil infrastructure systems. Thus, there is a need to extend the focus of traditional design …

The objective of this study is to investigate the influence of frequency content of ground
motions on the seismic fragility of nuclear power plant (NPP) equipment. Transfer functions …

The safety of nuclear power plants (NPPs) depends on the actions taken to prevent nuclear
accidents or to limit their consequences. This paper proposes improvement of pressurized …

Abstract Model updating is of significant importance in the actual analyses of real structures.
The differences between experimental and numerical dynamic characteristics can be …
