Near-real-time Identification of Seismic Damage by Graph Neural Network based on Structural Modes
(2023)This paper proposes a near-real-time damage identification method based on the graph neural network (GNN) using the structural response data recorded during an earthquake event. The proposed method features a structural-mode-based ... -
Near-real-time online process control using grey-box models
(2023)Near-real time control of dynamical processes is very beneficial as it enables detection and timely intervention in case of diminishing quality or necessary parameter adjustment. This can improve quality and reliability, ... -
Network Analysis of Systems of Systems Models for Complex Infrastructure Systems
(2023)Complex infrastructure systems, such as transportation and communication networks, consist of many interconnected and interdependent elements that exhibit behavior that is difficult to predict. Researchers have developed ... -
Network Reliability Analysis and Complexity Quantification Using Bayesian Network and Dual Representation
(2023)Modern society operates upon various lifeline networks such as transportation networks, power networks, and gas distribution networks. To secure their reliable operations, it is critical to evaluate their reliability. ... -
New insights for chemical-physical processes from analysis of observations using extreme value probability distributions
(2023)Conventional extreme value (EV) theory has the Gumbel EV distribution as the theoretically correct distribution to represent the maximum depth of corrosion pits. It has long been used for prediction of the probability of ... -
New opportunities for bridge management using independent datasets
(2023)Bridge managers have increasingly utilised databases to aid in the efficient allocation of resources. For the most part, these databases have been compiled from existing bridge management tools such as bridge inspection ... -
New versus Previous ASCE 7-16 Earthquake Loads for 500 Overseas Locations
(2023)The American Society of Civil Engineers (ASCE) Earthquake Loads Overseas project is an ongoing collaboration between the U.S. Geological Survey (USGS) and the Global Earthquake Model (GEM) Foundation to compute Risk-targeted ... -
Next Generation Community-Level Resilience Modeling: The Interdependent Networked Community Resilience Modeling Environment (IN-CORE)
(2023)In 2015, the U.S National Institute of Standards and Technology (NIST) funded the Center of Excellence for Risk-Based Community Resilience Planning (CoE), a 14 university-based consortium of almost 100 people, including ... -
Non-stationary response autocorrelation function of nonlinear oscillators endowed with fractional derivative elements
(2023)An approximate analytical technique is developed for determining the non-stationary response autocorrelation function of nonlinear oscillators endowed with fractional derivative elements. Specifically, first, a stochastic ... -
Nonlinear Model-Data Fusion with Minimal Sensing for Performance-Based Seismic Monitoring of Instrumented Buildings
(2023)This paper presents a new concept for performance-based monitoring (PBM) of instrumented buildings subject to earthquakes. This concept is achieved by simultaneously combining and advancing existing knowledge from structural ... -
On the similarity between discrete harmonic wavelet and discrete orthonormal S transform
(2023)Two efficient transforms: discrete harmonic wavelet transform (DHWT) and discrete orthonormal S transform (DOST) were developed in the literature. They can be used to analyze, model, and simulate nonstationary signals. ... -
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 ... -
Online Aleatory Uncertainty Quantification for Probabilistic Time Series Models
(2023)Engineering problems rely on probabilistic models for decision making tasks. One such approach are the state-space models used for time series forecasting which involve unknown parameters for not only modelling physical ... -
Optimal exploitation of sparsely localised traffic data for modelling traffic flow in road networks
(2023)Traffic flow data are generally collected using induction loops. Therefore, to capture traffic dynamics along road sections, a very fine mesh of induction loops is required. However, due to their higher cost of installation ... -
Optimal mechanical performance prediction of a sediment-based geopolymer road sub-layer
(2023)One of the major obstacles for the implementation of dredged sediment in the manufacture of concrete is its variable mineralogical properties. However, its use in the manufacture of geopolymer binder as proven to be an ... -
Optimal risk-based design of a RC frame under column loss scenario
(2023)Structural systems may be subject to abnormal loads with small probability of occurrence but great intensity, which may lead to local damage, and even loss of loadbearing elements. In this context, it is important to design ... -
Optimizing Crack Repair Policies using Value of Information Analysis considering Imperfect Inspection of Pipelines
(2023)This study presents an approach for optimizing policies on crack repair, which may take place after pipeline inspection, depending on the possible failure risk (i.e., the severity of crack) and the repair cost. The approach ... -
Optimizing the Bridge Maintenance Schedule of Transportation Networks under Uncertainty: A Simheuristic Approach Considering Reliability
