Reliability-Based Design Optimization of Frame-Supported Tensile Membrane Structures
(American Society of Civil Engineers, 2017)Due to the inherent flexibility of tensile membrane structures (TMS), they need to remain in a stable equilibrium condition in the presence of gusty winds as well as in their absence. This paper is aimed at the reliability-based ... -
Asset Risk Management and Resilience for Flood Control, Hydropower, and Waterways
(American Society of Civil Engineers, 2016)Natural disasters in the past decade have encouraged agencies responsible for development and maintenance of infrastructure systems toward the accounting of risk and resilience in asset management, buying down risks to ... -
Online Noise Identification for Joint State and Parameter Estimation of Nonlinear Systems
(American Society of Civil Engineers, 2016)The quality of structural parameter identification in nonlinear systems using Bayesian estimators, such as the unscented Kalman filter (UKF), depends heavily on the assumptions about the state and observation noise processes. ... -
Probabilistic Assessment of Serviceability Limit State of Diaphragm Walls for Braced Excavation in Clays

Adaptive Reliability Analysis of Reinforced Concrete Bridges Subject to Seismic Loading Using Nondestructive Testing
(American Society of Civil Engineers, 2015)Seismic fragility reflects the reliability of a structure to withstand future seismic demands. It is defined as the conditional probability that a structural demand attains or exceeds a specified capacity level for given ... -
Development of Reliability-Based Damage-Tolerant Optimal Design of Ship Structures
(American Society of Civil Engineers, 2015)While in service, ship structures are continuously subjected to environmental loading and deterioration, which could lead to increased inspection and maintenance costs during a vessel’s lifecycle. The design strategy ... -
Probabilistic Assessment of Debris Flow Peak Discharge by Monte Carlo Simulation
(American Society of Civil Engineers, 2017)The topographic and hydrologic parameters involved in the estimation of the debris flow peak discharge in a classical approach are usually assumed to be deterministic. As a result, in such approaches, the only uncertainty ... -
Simplified Seismic Analysis of Disordered Masonry Towers
(American Society of Civil Engineers, 2016)The structural assessment of existing masonry towers under exceptional loads, such as earthquake loads, requires reliable and expedite methods of analysis. These approaches should take into account both the specific nonlinear ... -
Empirical Comparison of Two Methods for the Bayesian Update of the Parameters of Probability Distributions in a Two-Level Hybrid Probabilistic-Possibilistic Uncertainty Framework for Risk Assessment
(American Society of Civil Engineers, 2016)In this paper, the authors address the issue of updating in a Bayesian framework, the possibilistic representation of the epistemically uncertain parameters of (aleatory) probability distributions, as new information ... -
Lifecycle Multihazard Framework for Assessing Flood Scour and Earthquake Effects on Bridge Failure
(American Society of Civil Engineers, 2016)A lifecycle multihazard framework is proposed to assess the system failure of bridge structures subjected to the combined hazards of flood-induced scour and earthquakes. The framework consists of three major components, ... -
Numerical Investigations into the Value of Information in Lifecycle Analysis of Structural Systems
