Semi-Markov Models for the Deterioration of Bridge Elements
Publisher: American Society of Civil Engineers
Abstract: Many bridge management systems (BMSs) use a Markov chain model to forecast the deterioration process. The Markov property may be considered to be restrictive when modeling the deterioration of transportation assets, primarily ...

Comparison of Markov Chain and Semi-Markov Models for Crack Deterioration on Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: There is a growing demand to preserve transportation infrastructure utilizing limited funds, and the modeling of flexible pavement deterioration has become an integral component of any pavement preservation model. Markov ...
Effect of Construction Induced Vibrations on Green Concrete in Drilled Shafts
Publisher: American Society of Civil Engineers
Abstract: This study was concerned with vibrations induced during drilled shaft construction on green concrete in adjacent drilled shafts. To characterize the types of vibrations, a full-scale field test was conducted using a 0.9-m ...
Reliability-Based Modeling of Bridge Deterioration Hazards
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results from a study on the deterioration patterns of highway bridges, using estimated sojourn times of bridge components in various deterioration states (condition). With emphasis on the age that ...
Performance Assessment of Deteriorating Bridge Channels in the Presence of Hurricane Failures: The Competing Risks Scenario
Publisher: ASCE
Abstract: Natural disasters such as hurricanes, earthquakes, and storm surges among other hazards affect communities and large geographic areas of the United States, resulting in negative repercussions on civil infrastructure. The ...
Multicriteria DSS with Historical Database for Attenuator Selection
Publisher: American Society of Civil Engineers
Abstract: A computerized information system has been developed for the management of field data on vehicle impacts with crash attenuators. The system has been developed for an intranet platform with a Java-based interface. A central ...
Pavement Crack Rating Using Machine Learning Frameworks: Partitioning, Bootstrap Forest, Boosted Trees, Naïve Bayes, and <i>K</i>-Nearest Neighbors
Publisher: American Society of Civil Engineers
Abstract: Deteriorating highway pavement conditions have largely been evaluated through visual inspection, nondestructive evaluations, smart sensing technologies, and image analysis techniques. These techniques have been successful ...
