Reliability updating in the presence of distribution parameter uncertainty
(2023)Reliability updating (RU) is often used to re-evaluate the failure probability of structural system when new observations are obtained. However, in engineering practice, the specific distribution parameters of input variables ... -
Efficient uncertainty analysis method for structures with hybrid uncertainty based on reduced-order model
(2023)An efficient uncertainty analysis method is proposed in this paper for structures with hybrid random and interval variables by using the idea of reduced-order model. In the proposed method, proper orthogonal decomposition ... -
Incorporation of Equity into Infrastructure Decision-Making: Development of an Equity Metric for Infrastructure Retrofitting
(2023)When infrastructure service outages occur, especially after natural hazards, the impacts are not felt uniformly across a community but are disproportionately clustered in vulnerable groups (e.g., low-income, minority, ... -
Lifetime reassessment of offshore wind turbines using meta-models
(2023)Offshore wind turbines are usually designed for 25 years. After this period, there are various options regarding the further use of the wind turbines. One option is a so-called lifetime extension, i.e., to continue operating ... -
A kriging metamodel with adaptive sampling for seismic evaluation of podium buildings
(2023)In this paper, nonlinear time-history dynamic analyses of selected earthquake ground motions are conducted on designated wood-frame podium buildings and the resulting inter-story drifts are analyzed. We aim to construct a ... -
Relevance of Uncertainty Modelling for Wind Turbine Lifetime Estimations
(2023)For the design of wind turbines, the determination of the fatigue lifetime is essential. Frequently, so-called lifetime "damage equivalent loads" (DELs) are used as a measure for the fatigue lifetime. Short-term DELs are ... -
Consistent Sensitivity Indices for p-Boxes
(2023)The main objective of global sensitivity analyses is to determine the influence of uncertain input parameters of a (simulation) model on the output parameters of the same model. Normally, for this purpose the uncertain ... -
Probabilistic finite element analyses of slope stability due to heavy rains: a comparison of homogeneous and spatially variable models
(2023)Consequences of the climate change like melting of the permafrost and the increasing number of extreme events like heavy rains are all factors which can increase the probability of occurrence of slope instability. For ... -
Wilting rationalism in technical decision making
(2023)Decision makers in diverse engineering disciplines, ranging from technical risk analysis and design to the development of risk-informed policies that impact on technology and society, benefit from the existence of a solid ... -
Sensitivity and reliability analyses applied to day-to-day geotechnical engineering using meta-models coupled with 3D finite elements
(2023)On one hand, finite element analyses have nowadays become a standard in order to design complex soil-structure interaction works, especially when dealing with sensitive structures in the vicinity of the project. On the ... -
Langevin Dynamics for Importance Sampling in Reliability Analysis
(2023)Importance Sampling (IS) is a popular simulation method for the reliability analysis of general engineering systems. Its core idea is to build a biased density that can sample from the failure domain more frequently than ... -
Climate Change Impacts on Flood-induced Industrial Building Losses in a Coastal City of Australia
(2023)Buildings in coastal cities of Australia, mostly located in estuarine and deltaic plains, are vulnerable to various types of floods. The adverse effects of flooding could be further exacerbated with global warming and sea ... -
Probabilistic Seismic Drift Demand on SMRF based on Extended Modal Analysis and Natural-Period-dependent Spectrum Intensity
(2023)The objectives of this study is to develop a framework for estimating the exceedance probability (pex) of the maximum inter-story drift ratio (ISDR) at each story of an SMRF on the basis of previously proposed techniques ... -
Calibration of load and resistance factors for the limit state-based assessment of dent-gouge defects on energy pipelines
(2023)Buried oil and gas pipelines are sometimes subjected to mechanical damage resulting from the impact with foreign objects such as excavation equipment or rocks. A severe form of the mechanical damage is the so-called ... -
Investigations on the effect of non-linear models on the reliability of partial safety factor designs
(2023)Most modern structural design codes, such as the Eurocode, are based on the partial safety factor concept. The partial safety factors are calibrated on linear limit states. They provide simplified rules on the application ... -
Time-Dependent Reliability Calculations Approximated by a Lower and Upper Bound Method to Determine Time-To-Failure Curve for Optimization of Interventions
(2023)The optimization of the timing of repair interventions on civil engineering structures is ideally based on the minimization of the total life-cycle cost. An important part of the total life-cycle cost is the expected failure ... -
Could rooftop solar panels and storage have enhanced the electricity resilience during Hurricane Isaias (2020)?
(2023)Hurricanes damage power systems extensively, causing large power outages, critical service disruptions, and major economic losses. Hurricane Isaias (2020) caused more than two million power outages in the U.S. that, in ... -
A performance-based probabilistic framework to model risk to power systems from hurricanes
(2023)Utility companies are often prepared for small-scale blackouts under normal operating conditions. However, they face crucial challenges with extreme weather events, such as hurricanes. Utilities must make risk-informed ... -
Applicability of meta-model assisted reliability assessment for dynamic problems: a comparison between regression-based methods
(2023)There is a growing intent among engineers, stakeholders, and decision makers to use probabilistic methods for infrastructure assessment or design objectives. However, the corresponding limit state for such problems usually ... -
Application of a decision sensitivity measure for the cost-benefit analysis of flood polders along the Bavarian Danube
(2023)The use of sensitivity measures to quantify the relative importance of model inputs and to assess the effect of uncertainties is an important part of risk analyses in engineering. In risk analysis, models serve to support ...
