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 ... -
Probabilistic Modelling of Soil Shear Strength by Maximum Entropy Quantile Functions
(2023)The 1990 Nipigon River landslide that occurred north of the township of Nipigon, northwestern Ontario, is listed among the catastrophic landslides in Canada. Since 1990, many additional landslides of various scale and ... -
Unified framework of stochastic structural dynamics: direct probability integral method
(2023)Stochastic dynamics of structures involves the topics of simulation of random excitation, random vibration analysis, reliability estimation and reliability-based design optimization. However, the existing methods only focus ... -
Finite dimensional surrogates for extreme events
(2023)Finite dimensional (FD) models are developed for random processes X(t) with continuous samples. The FD models Xd(t) are deterministic functions of time and finite sets of random variables which are defined on the same ... -
Effectiveness Assessment of Adaptation Measures to Build Wildfire Resilience of Road Networks
(2023)Wildfires have become a source of concern for society due to their increased frequency, intensity, and unpredictability. This has caused serious impacts all over the world, even in areas where this type of problem has not ... -
Reliability of RC shear walls with uncertainty of failure mode
(2023)The propagation of damage evolution at different scales leads to the uncertainty of failure mode for shear walls, and it is difficult to determine the reliability of shear walls with shear failure accurately using the ... -
Direct probability integral method-based system reliability sensitivity analysis and design optimization
(2023)System reliability-based design optimization (SRBDO) can take an optimal trade-off between economy and safety in structural design with multiple failure modes, in which the evaluation of system reliability and its sensitivity ... -
An efficient approach to reliability-based topology optimization of continuum structures with multimodal distributions
(2023)Reliability-based topology optimization (RBTO) considering uncertainties has attracted great attention recently. In practical applications, some random variables follow multimodal distributions, thus, RBTO with multimodal ... -
A hybrid approach for deriving probability distributions of rock mass discontinuity parameters for slope reliability analysis
(2023)It is widely recognized that the rock mass discontinuity properties (e.g., dip angle and dip direction, trace length and aperture, cohesion and friction) can greatly affect the stability of rock slope. The discontinuity ...
