Evaluating the Influence of Differing Geotechnical Risk Perceptions on Design-Build Highway Projects
(American Society of Civil Engineers, 2018)Managing geotechnical risk in design-build (DB) projects is complicated because the contract is awarded before a thorough subsurface investigation is conducted, making geotechnical uncertainty high during bid preparation. ... -
Systematic Reliability-Based Approach to Progressive Collapse
(American Society of Civil Engineers, 2018)Recent structural failures in buildings, occurring in a progressive way, have raised awareness of the profession toward the need for robustness in structural design. However, systematic approaches for robust design, ... -
Resilience Assessment of Overhead Power Distribution Systems under Strong Winds for Hardening Prioritization
(American Society of Civil Engineers, 2018)During extreme weather and other emergency conditions, the safety and resilience of the overhead power distribution system is essential for communities. Quick detection of damaged poles and wires as well as quick recovery ... -
Reliability-Based Performance of Embankments Improved with Deep Mixing Considering Spatial Variability of Material Properties
(American Society of Civil Engineers, 2018)Geotechnical structures are generally designed using the deterministic approach, where uniform properties are used over the material space. This approach is not appropriate for deep cement mixed (DCM) ground due to the ... -
Bowtie Analysis without Expert Acquisition for Safety Effect Assessments of Cooperative Intelligent Transport Systems
(American Society of Civil Engineers, 2018)Estimating the safety effects of emerging or future technology based on expert acquisitions is challenging because the accumulated judgment is at risk to be biased and imprecise. Therefore, this semiquantitative study is ... -
Urban Heat Projections in a Changing Climate: Washington, DC, Case Study
(American Society of Civil Engineers, 2018)Climate change has been shown to elevate urban temperatures, intensify extreme heat events, and raise heat exposure risks in cities. Characterizing the future trends and levels of heat-related problems is important in order ... -
Soil–Structure Interaction in Seismic Design Code: Risk-Based Evaluation
(American Society of Civil Engineers, 2018)This paper puts forward a risk-based approach to investigate the consequences of practicing soil–structure interaction (SSI) provisions of modern seismic design codes. The proposed approach computes the probability that ... -
Control Variate Approach for Efficient Stochastic Finite-Element Analysis of Geotechnical Problems
(American Society of Civil Engineers, 2018)Monte Carlo simulation is the most versatile solution method for problems in stochastic computational mechanics but suffers from a slow convergence rate. The number of simulations required to produce an acceptable accuracy ... -
Failure Probability of Transverse Surface Settlement Induced by EPB Shield Tunneling in Clayey Soils
(American Society of Civil Engineers, 2018)This paper compiles a database consisting of 16 tunnel excavation projects in clayey soils using the earth pressure balance (EPB) tunneling method. Statistical analysis of the data is performed and the probability distributions ... -
Bivariate Severity Analysis of Train Derailments using Copula-Based Regression Models
(American Society of Civil Engineers, 2018)The far-reaching consequences of train derailments have been a major concern to industry and government despite their relatively low occurrence. These consequences include injury, loss of life and property, interruption ... -
Extreme Precipitation Analysis and Prediction for a Changing Climate
(American Society of Civil Engineers, 2018)Extreme precipitation is one of the most important climate hazards that pose a significant threat to human property and life. Understanding extreme precipitation events helps to manage their risk to society and hence reduce ... -
Tolerance Analysis of a Deformable Component Using the Probabilistic Approach and Kriging-Based Surrogate Models
(American Society of Civil Engineers, 2018)Tolerance analysis is a key issue in proving the compatibility of manufacturing uncertainties with the quality level of mechanical systems. For rigid and isostatic systems, multiple methods (worst case, statistical, or ... -
Scenario Analysis and PERT/CPM Applied to Strategic Investment at an Automated Container Port
(American Society of Civil Engineers, 2018)Particular scenarios of emergent and future conditions are more disruptive than others in terms of project schedules and the evolving priorities of project managers. It is essential to associate the scenarios with cost and ... -
Peak Strength Expression for Concrete Confined with Fiber-Reinforced Polymer
(American Society of Civil Engineers, 2018)This study obtains a three-dimensional unified peak strength expression for confined concrete from the reported experimental results of circular concrete columns confined with different fiber-reinforced polymer (FRP) ... -
Prediction of Weather-Related Incidents on the Rail Network: Prototype Data Model for Wind-Related Delays in Great Britain
(American Society of Civil Engineers, 2018)The impacts of extreme weather events on railway operations are complex and in the most severe cases can cause significant disruption to the rail services, leading to delays for passengers and financial penalties to the ... -
Robust Bayesian Reliability for Complex Systems under Prior-Data Conflict
(American Society of Civil Engineers, 2018)This paper considers the quantification of system reliability in scenarios in which data, that is, failures or the absence of failures, occurring from the system’s use over time, are considered surprising from the perspective ... -
New Seismic Vulnerability Index for Vertically Irregular Buildings
(American Society of Civil Engineers, 2018)Most international design codes either prohibit construction or recommend alternative seismic analysis and design of vertically irregular building frames, depending on the degree of irregularity and site hazard. However, ... -
Probabilistic Model for Regional Multiseverity Casualty Estimation due to Building Damage Following an Earthquake
