Vulnerability Assessment of Health Care Facilities during Disaster Events
(American Society of Civil Engineers, 2009)Infrastructure systems are essential to the operation of health care facilities and do not exist in isolation of one another—telecommunications networks require electricity, transportation networks require systems information ... -
Reliability Estimation for Networks of Reinforced Concrete Bridges
(American Society of Civil Engineers, 2009)Transportation networks are critical lifelines and their functionality after an earthquake is of primary importance for life safety and economic recovery of a community, yet they can be severely damaged during earthquakes. ... -
Optimization Model for Design and Operation of Transportation Networks in Seismic Regions
(American Society of Civil Engineers, 2009)Large infrastructure systems (e.g., transportation networks) cannot be designed and operated based only on standard regulations provided by codes of practice and operations manuals. It is necessary to consider not only ... -
Water Utility Efficiency Assessment Using a Data Envelopment Analysis Procedure
(American Society of Civil Engineers, 2009)Data envelopment analysis is used to compare the relative efficiencies of potable water utilities using the United States Environmental Protection Agency community water system survey data. Three ownership types (private ... -
Planning for Evacuation: Insights from an Efficient Network Design Model
(American Society of Civil Engineers, 2009)In the context of evacuation planning at a strategic level, an efficient model is proposed to augment network capacity under a budget constraint so as to enhance operational performance under a security threat. Contraflow ... -
Discussion of “Productivity Study of Microtunneling Pipe Installation Using Simulation” by Roy Yu Luo and Mohammad Najafi
(American Society of Civil Engineers, 2009) -
Multiperiod Competition in an Electric Power Network and Impacts of Infrastructure Disruptions
(American Society of Civil Engineers, 2009)This paper puts forth a dynamic, game theoretic model of oligopolistic competition in electric power markets. The purpose of this model is to allow one to quickly and efficiently test the effects of changes to the capacity ... -

Dynamic Bayesian Network for Predicting the Likelihood of a Terrorist Attack at Critical Transportation Infrastructure Facilities
(American Society of Civil Engineers, 2009)This research is motivated by the increased awareness for terrorism related research in the post- -
Integrated Scheme for Olympic Village Traffic and Parking Arrangements
(American Society of Civil Engineers, 2009)The present study deals with the development of an integrated transportation scheme serving the needs of guests at an Olympic Village during the 2004 Athens Olympics. The Olympic Village was located at the port of Piraeus ... -
Preparing an Airport for the Olympic Games: Athens
(American Society of Civil Engineers, 2009)Athens International Airport served as the principal gateway to Greece for athletes and the Olympic Family and for the general public during the Olympic Games of 2004. The airport’s performance during the Games was universally ... -
Evaluation of Water-Repelling Additives for Use in Concrete-Based Sanitary Sewer Infrastructure
(American Society of Civil Engineers, 2009)Laboratory and field investigations were conducted in order to evaluate the effectiveness of water-repelling additives in reducing the microbial-induced corrosion of concrete-based infrastructure in sanitary sewer systems. ... -
Using Water Main Break Data to Improve Asset Management for Small and Medium Utilities: District of Maple Ridge, B.C.
(American Society of Civil Engineers, 2009)An approach is developed for identifying key data to be used in asset management in general, and for predicting pipe breaks and selecting appropriate models in particular. The approach is applied to the District of Maple ... -
Transportation Infrastructure Maintenance Management: Case Study of a Small Urban City
(American Society of Civil Engineers, 2009)A transportation infrastructure maintenance management system (TIMMS) for a small urban city is developed. Uintah, Utah, year 2005 population 2,000, is studied. As of Fall 2001, this suburb of the Salt Lake City–Ogden urban ... -
Infrastructure Management: Integrated AHP/ANN Model to Evaluate Municipal Water Mains’ Performance
(American Society of Civil Engineers, 2008)Canadian municipalities have noted that 59% of their water systems needed repair and the status of 43% of these systems is unacceptable. In the United States, ASCE assigned a near failing grade of D– to the condition of ... -
Nondestructive Testing and Evaluation of Concrete Parking Garages
