A new methodology for modeling explicit seismic common cause failures for seismic multi-unit probabilistic safety assessment

open access: yesNuclear Engineering and Technology, 2020
In a seismic PSA, dependency among seismic failures of components has not been explicitly modeled in the fault tree or event tree. This dependency is separately identified and assigned with numbers that range from zero to unity that reflect the level of ...

Introducing the STAMP method in road tunnel safety assessment [PDF]

open access: yes, 2012
After the tremendous accidents in European road tunnels over the past decade, many risk assessment methods have been proposed worldwide, most of them based on Quantitative Risk Assessment (QRA).

Probabilistic Assessment of Buildings Subjected to Multi-Level Earthquake Loading Based on the PBSD Concept

open access: yesBuildings, 2022
An alternative probabilistic assessment of buildings excited by multi-level seismic loading is presented in this paper. This evaluation is developed for both steel and reinforced concrete buildings using the Performance-Based Seismic Design (PBSD ...

Seismic Rigoletto: Hazards, risks and seismic roulette applications

open access: yesFrontiers in Earth Science, 2023
Neo-Deterministic Seismic Hazard Assessment (NDSHA), dating back to the turn of the Millennium, is the new multi-disciplinary scenario- and physics-based approach for the evaluation of seismic hazard and safety–guaranteeing “prevention rather than cure.”

Seismic reliability assessment of a non-seismic reinforced concrete framed structure designed according to ABNT NBR 6118:2014

open access: yesRevista IBRACON de Estruturas e Materiais, 2021
: Due to the paucity of studies regarding the seismic assessment of buildings in Brazil, this study aims to present and discuss a seismic reliability assessment of a reinforced concrete framed structure designed according to the Brazilian standard ABNT ...

Probabilistic Seismic Analysis of the Deep Sliding Stability of a Concrete Gravity Dam-Foundation System

open access: yesAdvances in Civil Engineering, 2020
There are various uncertainties in the design, construction, and operation of dams. These uncertainties have an important impact on the seismic response and seismic safety evaluation of concrete dams. In this research, a typical nonoverflow monolith of a

Uncertainty analysis of large risk assessment models with applications to the railway safety and standards board safety risk model [PDF]

open access: yes, 2009
Probabilistic risk analysis aims to assess the safety risk of a system so that actions can then be taken to improve safety. Uncertainty however always exists in modelling. For more informed decision making, uncertainty in the outputs of the model must be

On improving seismic risk and cost for nuclear energy facility based on multi-objective optimization considering seismic correlation

open access: yesEnergy Reports, 2022
Currently, the system, structure, and component (SSC) seismic design and seismic probabilistic safety assessment (SPSA) process for the nuclear energy facility are performed individually, thus seismic risk reduction and cost efficiency cannot be pursued.
