RISMethodology to Quantitatively Assess Impacts of 5G Telecommunications Cybersecurity Risk Scenarios on Dependent Connected Urban Transportation Systems
Publisher: ASCE
Abstract: The fifth generation (5G) technology standard for cellular networks is currently being developed and is in the early stages of rollout across the United States. This upgrade from 4G LTE (long-term evolution) will not only ...
Time-Series Prediction in Nodal Networks Using Recurrent Neural Networks and a Pairwise-Gated Recurrent Unit Approach
Publisher: ASCE
Abstract: Characteristics at nodes in a network, such as values of demand, evolve over time. To make time-dependent decisions for a network, making time series predictions at each node in the network over time is often necessary. ...
Framework for Probabilistic Assessment of Maximum Nonlinear Structural Response Based on Sensor Measurements: Discretization and Estimation
Publisher: American Society of Civil Engineers
Abstract: A probabilistic framework to draw real-time inferences on the maximum response of an uncertain nonlinear structural system under stochastic excitation based on sensor measurements is proposed. The primary contributions are ...
Methodology for Regularization of Force-Based Elements to Model Reinforced Concrete Columns with Short Lap Splices
Publisher: ASCE
Abstract: In reinforced concrete structures built before the 1970s, it was common for columns to be constructed with short lap splices and widely spaced transverse bars at the column base, leading to increased likelihoods of pull-out ...
Algorithms for Bayesian Network Modeling, Inference, and Reliability Assessment for Multistate Flow Networks
Publisher: American Society of Civil Engineers
Abstract: The Bayesian network (BN) is a useful tool for the modeling and reliability assessment of civil infrastructure systems. For a system comprising many interconnected components, it captures the probabilistic dependencies ...
Impacts of Climate Change on the Assessment of Long-Term Structural Reliability
Publisher: American Society of Civil Engineers
Probability Propagation Method for Reliability Assessment of Acyclic Directed Networks
Publisher: American Society of Civil Engineers
Abstract: Many civil infrastructure systems that deliver resources from source points to sinks, e.g., power distribution and gas pipeline networks, can be described as acyclic directed networks comprising nodes and links. ...
Combined Effects of Soil Stress History and Scour Hole Dimensions on Laterally and Axially Loaded Piles in Sand and Clay under Scour Conditions
Publisher: ASCE
Abstract: Removal of soil around a bridge foundation due to scour results in a reduction of the lateral and vertical foundation capacity due to the loss of soil support. The common approach in modeling the scour phenomenon of removal ...
Framework for Probabilistic Vulnerability Analysis of Interdependent Infrastructure Systems
Publisher: American Society of Civil Engineers
Abstract: Critical infrastructure systems are deteriorating and experiencing increased cascading failures. In this paper, we propose a new probabilistic framework for modeling interdependent infrastructure networks. As part of this ...
Reliability Assessment of Critical Infrastructure Using Bayesian Networks
Publisher: American Society of Civil Engineers
Abstract: The authors present a Bayesian network (BN)-based approach for modeling and reliability assessment of infrastructure systems. The BN is a powerful framework that is able to account for uncertainties in component and system ...
