Implementing the Extended Multivariate Approach in Design with Partial Factors for a Retaining Wall in Clay
(American Society of Civil Engineers, 2017)Limitations with the current design using partial factors in Eurocode 7 have been identified. Uncertainties in the material properties are incorporated in both the cautious estimate of the characteristic value and the ... -
Analyzing Impact on Critical Infrastructure Using Input-Output Interdependency Model: Case Studies
(American Society of Civil Engineers, 2017)The economic input-output interdependency model is a quick decision tool for stakeholders of critical infrastructure to understand the economic impact of a disruptive event. To demonstrate its applications, two real case ... -
Prediction of Pipe Failure by Considering Time-Dependent Factors: Dynamic Bayesian Belief Network Model
(American Society of Civil Engineers, 2017)The water supply system (WSS) is a lifeline of the modern city. Transmission and distribution pipes, spatially distributed components of the WSS, are most often vulnerable to failure (leakage, breakage, or burst). Many ... -
Advanced Monte Carlo Methods and Applications

Sources of Uncertainty in Site Characterization and Their Impact on Geotechnical Reliability-Based Design
(American Society of Civil Engineers, 2017)Different variabilities and uncertainties (e.g., inherent variability, measurement errors, statistical uncertainty, and transformation uncertainty) in site characterization are usually lumped together as total variability ... -
Probabilistic Stratification Modeling in Geotechnical Site Characterization
(American Society of Civil Engineers, 2017)Stratification in geologic profiles is one of the most significant uncertainties in geotechnical site characterization. In this paper, a three-level probabilistic framework is proposed for geotechnical stratification ... -
Uncertainty Quantification of Power Spectrum and Spectral Moments Estimates Subject to Missing Data
(American Society of Civil Engineers, 2017)In this paper, the challenge of quantifying the uncertainty in stochastic process spectral estimates based on realizations with missing data is addressed. Specifically, relying on relatively relaxed assumptions for the ... -
Economic and Societal Challenges Imposed by Seismic Risk on the Built Environment
(American Society of Civil Engineers, 2017)Earthquakes kill approximately 20,000 persons per annum, with the peak annual loss rate in the last 120 years estimated at 280,000 humans. There are four broad categories of earthquake of interest, ones that ... -
Probabilistic Assessment and Cost-Benefit Analysis of Nonductile Reinforced Concrete Buildings Retrofitted with Base Isolation: Considering Mainshock–Aftershock Hazards
(American Society of Civil Engineers, 2017)Nonductile reinforced concrete (RC) frame buildings were found to be vulnerable to earthquakes. Thus retrofitting of these buildings is necessary, as addressed in the recent retrofit program of Los Angeles. A potential ... -
Detection of Stationary Markovian Zones in a Geologically Heterogeneous Area
(American Society of Civil Engineers, 2017)The stationary Markov process model is widely used to predict the geological conditions in tunnel excavation projects. However, the validity of the stationary assumption made in the model is questionable. The prediction ... -
Statistical Investigation of Effective Prestress in Prestressed Concrete Bridges
(American Society of Civil Engineers, 2017)The effective pretress of a strand is very important for prestressed concrete (PC) bridges because it can influence cracking and deflections. At present, the effective prestress is obtained by means of calculating the ... -
Risk Assessment in Quantification of Hurricane Resilience of Residential Communities
(American Society of Civil Engineers, 2017)This paper proposes a framework to evaluate hurricane resilience of residential communities. Building resilience often refers to community resilience instead of individual resilience. Few efforts have been made to relate ... -
Estimating Peaks of Stationary Random Processes: A Peaks-over-Threshold Approach
(American Society of Civil Engineers, 2017)Estimating properties of the distribution of the peak of a stochastic process from a single finite realization is a problem that arises in a variety of science and engineering applications. Furthermore, it is often the ... -
Robust and Reliability-Based Structural Topology Optimization Using a Continuous Adjoint Method
(American Society of Civil Engineers, 2016)A unified framework for robust and reliability-based structural topology optimization, considering structural model and loading uncertainties, is presented using a continuous adjoint formulation. The topology optimization ... -
Risk Assessment for Stream Modification Projects in Urban Settings
(American Society of Civil Engineers, 2015)The dynamic and stochastic nature of riverine ecosystems creates considerable uncertainty within the practice of stream modification. For streams in urban environments, this uncertainty results in risk to the environment ... -
Blast Design-Basis Threat Uncertainty and Its Effects on Probabilistic Risk Assessment
(American Society of Civil Engineers, 2015)At present, the deterministic approach to blast-resistant design appears to be the prevalent philosophy in practice, as suggested by the notion of design-basis threat (DBT) outlined by the ASCE/SEI 59-11. In this study, ... -
Parametric Statistical Moment Method for Damage Detection and Health Monitoring
(American Society of Civil Engineers, 2016)This paper enriches the statistical moment-based damage detection method with approximate parametric solutions of the stationary second-order moments of nodal displacements and velocity, which are explicitly related to ... -
Hamiltonian Monte Carlo and Borrowing Strength in Hierarchical Inverse Problems
(American Society of Civil Engineers, 2016)Bayesian approaches to uncertainty quantification and information acquisition in hierarchically defined inverse problems are presented. The techniques comprise simple updating, staged estimation, and multilevel model ... -
Multicriteria Decision Analysis Approach for Stochastic Ranking with Application to Network Resilience
(American Society of Civil Engineers, 2016)Stochastic ranking, or the ordered comparison of alternatives whose performance is measured with random variables, is often made by relating expected values. Doing so ignores variability in performance, leaving the possibility ... -
