An efficient strategy for reliability-based design optimization of linear structural dynamic systems by the cross-entropy method
(2023)Engineering structures should be designed to minimize construction costs and maintain safety. Structural performance can be seldomly characterized deterministically, as many parameters, such as the material properties, ... -
On the Value of Information forecasting with multi-information systems
(2023)The deterioration of structural components together with the climate and mobility increasing demands undermine civil structuresﾒ safety and functionality performance. Planning of maintenance activities is necessary, along ... -
Probabilistic Risk Assessment of Electric Power Infrastructure Subjected to Earthquake-Induced Landslides
(2023)We develop a probabilistic framework to assess the vulnerability of electric power transmission structures to shallow landslides induced by earthquake ground shaking. We probabilistically describe possible damage states ... -
Risk Targets for Recovery-Based Design of Individual Buildings Considering Regional Performance
(2023)The development of risk-targeted design loads for recovery-based design first requires consensus around acceptable levels of building risk, specifically in terms of recovery-based performance objectives such as reoccupancy ... -
Quantitative modelling of human health risks arising from pesticide use in Irish agriculture
(2023)Pesticides have been identified as a growing concern due to the risk they pose to human health. Risk models can be used to predict pesticide concentrations in drinking water and analyse the associated health risks and hence ... -
Seismic reliability assessment of slopes subjected to stochastic pulse-like ground motions
(2023)Near-fault pulse-like ground motions attract increasing attention in engineering because they tend to cause more severe damage to structures than ordinary ground motions. Landslides, as the most common natural hazard ... -
Facilitating optimal people-centered risk-informed infrastructure design in growing cities, through a holistic lens
(2023)Past events around the world have highlighted the vulnerability of critical infrastructure to natural and anthropogenic hazards, which result in disruptions that have significant societal consequences. Many previous studies ... -
Considerations for the Development of Evidence Theory Applications
(2023)Evidence theory provides a natural framework for analyzing imprecise probabilities. Evidence theory enables the explicit recognition of ignorance and is therefore suited for the analysis of missing or incomplete data. This ... -
Reliability of structural dynamic systems
(2023)In this paper we shall discuss the use of the multidimensional ACER method to estimate the reliability of a series structural system where the components can be modelled as stochastic processes and where failure is associated ... -
Geometry of the failure set (system events) : impact on the efficiency of simulation methods, adaptations of some standard methods
(2023)System events (intersection or union of events - failure or safety domains) are of frequent interest in Structural Reliability, even for simple structures that are not mechanical systems. Intersections can be found when ... -
Probabilistic Flood Hazard Maps: a Bayesian Approach
(2023)Computing the likelihood of different events that might deal damage to built infrastructure and human lives is a key step in every rigorous risk analysis. Generally speaking, this is done by the mathematical concatenation ... -
Probabilistic time series modelling using Bayesian neural networks
(2023)Interpretable models play a key role in structural health monitoring (SHM) systems dealing with time series data. Interpretable models provide users with meaningful insights extracted from the raw data such as the level ... -
Including Epistemic Uncertainty in Engineering Decision Making
(2023)Most engineering systems are designed on the basis that their probability of under- performance is appropriately low. This is done either explicitly, by calculating this probability of failure, or implicitly, by prescribing ... -
Interpretation and analysis of deep reinforcement learning driven inspection and maintenance policies for engineering systems
(2023)In the wake of recent Deep Reinforcement Learning (DRL) breakthroughs in various fields, DRL-based approaches have also been successfully developed for the management of engineering systems, reaching performance that ... -
QUANTIFYING UNCERTAINTIES IN THE PERFORMANCE PREDICTION OF EXISTING CONCRETE STRUCTURES USING AN EXTENDED DIRECT STIFFNESS METHOD APPROACH
(2023)Reinforced concrete structures are widely used in many industrialized countries. Currently, significant parts of the patrimony in these regions are reaching the end of their lifetime. As a result, the through-life analysis ... -
Panel-Oriented Surrogate Model for Developing Class Fragility Curves for Transmission Towers
(2023)A panel-oriented surrogate model for classes (or portfolios) of transmission towers is presented. The surrogate model can be implemented as a beam-column element, whose validity is established through rigorous abstraction ... -
Reliability Analysis using Multiple Low-fidelity Models Coupled with Active Learning: A Robust, General, and Explainable Framework
(2023)To assess the reliability of critical technologies like nuclear plants and infrastructure systems and improve the robustness of design, engineers have to quantify the uncertainties surrounding the system behavior accurately. ... -
A DPIM-based framework for reliability analysis of building structures under stochastic near-fault ground motions
(2023)Near-fault ground motions have the forward directivity effect and fling-step effect, both of which can produce the distinct long-period pulse in velocity time histories. Such velocity pulses with larger amplitude easily ... -
Risk management strategies and probabilistic failure pressure model development for pipelines with crack-like defect
(2023)Optimal inspection and maintenance planning for deteriorating pipelines is necessary for cost-effective risk management decisions. The objective of this study is to develop a framework for determining the optimal inspection ... -
A review of stochastic live load models for code calibration
(2023)Reliability-based calibration of partial safety factors of structural design codes requires suitable stochastic models for, among others, live loads. These models need to be compatible with the design values and exceedance ...
