Uncertainty Quantification and Structural Reliability Estimation Considering Inspection Data Scarcity
(American Society of Civil Engineers, 2015)Reliability estimation of aging RC structures under environmental attack involves various sources of uncertainties. In realistic operational conditions, uncertainties due to limited number of experimental data and incomplete ... -
Reliability of Linear Systems Subjected to Wind Loads
(American Society of Civil Engineers, 2016)Probabilistic models for wind loads are developed and used to estimate the properties of the responses of linear systems. This analysis involves four steps. First, along-wind, across-wind forces, and torque are represented ... -
Engineering Decisions under Risk Averseness
(American Society of Civil Engineers, 2015)Engineering decisions are invariably made under substantial uncertainty about current and future system cost and response, including cost and response associated with low-probability, high-consequence events. A risk-neutral ... -
Probabilistic Model for Modal Properties Based on Operational Modal Analysis
(American Society of Civil Engineers, 2016)Operational modal analysis allows one to identify the modal properties (natural frequencies, damping ratios, mode shapes, etc.) of a constructed structure based on output vibration measurements only. For its high economy ... -
Softening Duffing Oscillator Reliability Assessment Subject to Evolutionary Stochastic Excitation
(American Society of Civil Engineers, 2016)An approximate analytical technique for assessing the reliability of a softening Duffing oscillator subject to evolutionary stochastic excitation is developed. Specifically, relying on a stochastic averaging treatment of ... -
Bayesian Approach for the Seismic Fragility Estimation of a Containment Shell Based on the Formation of Through-Wall Cracks
(American Society of Civil Engineers, 2016)The primary containment (PC) in a nuclear power plant provides the last barrier against radiation leakage to the environment. Design specifications fail to assess the performance of a seismically-damaged containment against ... -
Development of Flood Inundation Maps and Quantification of Flood Risk in an Urban Catchment of Brahmaputra River
(American Society of Civil Engineers, 2017)Flood inundation mapping (FIM) is required to understand the affects of flooding in a particular area and on important structures such as roadways, railways, streets, buildings and airport. FIM provides important information, ... -
Reliability-Based Optimal Design of Steel Box Structures. I: Theory
(American Society of Civil Engineers, 2015)A steel box structural design has been traditionally used for bridges and surface marine vessels and is on the basis of engineering experience/judgment and deterministic approaches, such as working stress design. Recent ... -
Reliability-Based Optimal Design of Steel Box Structures. II: Ship Structure Applications
(American Society of Civil Engineers, 2015)Traditional design of ship structures relies on a combination of experience, sound judgment, and deterministic approaches and typically ignores the potential for design improvement and other benefits offered through the ... -
Empirical Bayes Approach for Developing Hierarchical Probabilistic Predictive Models and Its Application to the Seismic Reliability Analysis of FRP-Retrofitted RC Bridges
(American Society of Civil Engineers, 2015)This paper proposes a general formulation to develop hierarchical probabilistic predictive models for clustered data. The common clustering factor, shared among the data within a group, causes statistical dependence that ... -
Application of Fuzzy Pattern Recognition of Seismic Damage to Concrete Structures
(American Society of Civil Engineers, 2015)There has been a long-standing desire to identify classes or groupings of buildings that exhibit similar characteristics in response to seismic events. Regional earthquake loss models, post-earthquake safety evaluations, ... -

Climate Impact Risks and Climate Adaptation Engineering for Built Infrastructure
(American Society of Civil Engineers, 2015)A changing climate may increase the frequency or intensity of natural hazards, resulting in increased infrastructure damage. The paper will describe how risk-based approaches are well suited to optimising climate adaptation ... -
Integrating Bayesian Linear Regression with Ordered Weighted Averaging: Uncertainty Analysis for Predicting Water Main Failures
(American Society of Civil Engineers, 2015)Water distribution networks (WDNs) are among the most important and expensive municipal infrastructure assets that are vital to public health. Municipal authorities strive for implementing preventive (or proactive) programs ... -
Practical Resilience Metrics for Planning, Design, and Decision Making
(American Society of Civil Engineers, 2015)Natural disasters in 2011 alone resulted in $366 billion (2011 US$) in direct damages and 29,782 fatalities worldwide. Storms and floods accounted for up to 70% of the 302 natural disasters worldwide, with earthquakes ... -
Framework for Post-Earthquake Risk Assessment and Decision Making for Infrastructure Systems
(American Society of Civil Engineers, 2015)The Bayesian network (BN) and influence diagram (ID) are used to develop a framework for post-earthquake risk assessment and decision making for infrastructure systems. The BN is used to model the earthquake hazard and ... -
Climate and Related Uncertainties Influencing Research and Development Priorities
