Transportation-Based Framework for Deriving Perturbations to the Inoperability Input-Output Model
(American Society of Civil Engineers, 2008)The Inoperability Input-Output Model (IIM) provides a mechanism to enable examination of interdependencies among economic sectors to estimate the effects of a disruptive event. In previous IIM applications, parametric ... -
Impact of Urban Form on Energy Use in Water Distribution Systems
(American Society of Civil Engineers, 2008)The paper explores the connection between the urban form of water distribution networks and their energy use. Urban form corresponds to the network pipe configuration and the spatial distribution of water users. An analytical ... -
Estimating Construction Project Environmental Effects Using an Input-Output-Based Hybrid Life-Cycle Assessment Model
(American Society of Civil Engineers, 2008)The design and construction industries have an increasing interest in and responsibility for a building’s environmental effects over its entire life cycle. Quantification of all building phases is important in life-cycle ... -
Financial and Operational Performance Assessment of Water/Wastewater Utilities: Comparative Study
(American Society of Civil Engineers, 2008)The water and wastewater sector is currently placed among infrastructure utilities of significance. A key problem with most water and wastewater utilities is the absence of performance assessment tools. This research focuses ... -
Temporospatial Analysis of Hurricane Katrina Regional Evacuation Traffic Patterns
(American Society of Civil Engineers, 2009)Between the fall of 2004 and spring of 2005, a plan was developed to facilitate the evacuation of southeast Louisiana, including the City of New Orleans, when under the threat of a hurricane. The plan was created by the ... -
Infrastructure Planning, Design, and Management for Big Events

Integrated Life-Cycle Assessment and Life-Cycle Cost Analysis Model for Concrete Bridge Deck Applications
(American Society of Civil Engineers, 2008)An integrated life-cycle assessment and life-cycle cost analysis model was developed and applied to enhance the sustainability of concrete bridge infrastructure. The objective of this model is to compare alternative bridge ... -
Impact Assessment and Remediation Strategies for Roadway Construction in Acid-Bearing Media: Case Study from Mid-Appalachia
(American Society of Civil Engineers, 2008)The likelihood of encountering land impacted by current and/or historic coal mining activities is high when constructing roadways in the Mid-Appalachian region. Through additional disturbance of these lands, environmental ... -
Community Investment Programs in Developing Country Infrastructure Projects
(American Society of Civil Engineers, 2008)Private sector infrastructure companies operating in developing countries can positively affect the social, environmental, and economic fabric of local communities by providing infrastructure services and through community ... -
Municipal Infrastructure Asset Levels of Service Assessment for Investment Decisions Using Analytic Hierarchy Process
(American Society of Civil Engineers, 2008)A given infrastructure system has different levels of service (LOS) for different users. To date, limited work has been done to combine these LOS to an asset level LOS. In addition, existing methods to determine LOS are ... -
Alternative Transportation Fuels: Distribution Infrastructure for Hydrogen and Ethanol in Iowa
(American Society of Civil Engineers, 2008)Ethanol and hydrogen are receiving considerable attention as alternative fuels for transportation. They are being promoted to reduce greenhouse gas emissions and improve U.S. energy independence. This paper analyzes pipeline, ... -
Levee Performance Assessment Methods Integrated in a GIS to Support Planning Maintenance Actions
(American Society of Civil Engineers, 2008)In recent years, there have been many failures of flood levees (river embankments) in France following river floods. The levees are mostly old structures for which few records are available. The matter is further complicated ... -
Full-Scale Experimental Determination of Concrete Pipe Joint Behavior and Its Modeling
(American Society of Civil Engineers, 2008)As a consequence of unequal loading or variable soil conditions, longitudinal bending of buried gravity pipes leads to circumferential pipe cracking or joint opening, which results in groundwater infiltration or leakage. ... -
Agent-Based Modeling: Approach for Improving Infrastructure Management
(American Society of Civil Engineers, 2008)Despite purported increases in infrastructure investment and widespread adoption of new technologies and management systems to support efficient and effective decision making, studies continue to document the poor condition ... -

Novel Methodology for Nondestructive Evaluation of Brick Walls: Fuzzy Logic Analysis of MASW Tests
(American Society of Civil Engineers, 2008)This paper presents a novel methodology for the nondestructive evaluation of brick walls using fuzzy logic and summarizes the results of the nondestructive evaluation of the relative condition of a sidewall of a brick ... -
Empirical Comparison of Statistical Pavement Performance Models
(American Society of Civil Engineers, 2008)We conduct an empirical comparison of nine representative statistical pavement performance models, which have been estimated using serviceability data from the AASHO Road Test. The purpose of the study is to understand the ... -
Energy Harvesting for Structural Health Monitoring Sensor Networks
(American Society of Civil Engineers, 2008)This paper reviews the development of energy harvesting for low-power embedded structural health monitoring (SHM) sensing systems. A statistical pattern recognition paradigm for SHM is first presented and the concept of ... -
