Computational Modeling of Existing Damage in Concrete Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: The research program discussed in this paper included both experimental and computational investigations of structural capacity effects on bridge columns by simulating observed column damage. For the experimental research, ...
Live Load Tests of the San Antonio “Y”
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of static live load tests performed on several spans of the San Antonio “Y” Project, Phase IIC, prior to its opening to traffic. The San Antonio “Y” Project is an urban viaduct comprising ...
Closure to “Measurements of Thermal Gradients and their Effects on Segmental Concrete Bridge” by Carin L. Roberts- Wollman, John E. Breen, and Jason Cawrse
Publisher: American Society of Civil Engineers
Measurements of Thermal Gradients and their Effects on Segmental Concrete Bridge
Publisher: American Society of Civil Engineers
Abstract: This paper presents concrete temperature data through the depth of a segmental box girder bridge. These data were collected continuously over a
Simulated Field Testing of High Performance Grouts for Post-Tensioning
Publisher: American Society of Civil Engineers
Abstract: A series of fresh property tests and accelerated corrosion tests were used to develop grouts that combine favorable grouting properties with good corrosion protection. The grouts were then pumped into a clear duct with ...
Effects of Transverse Prestressing in Bridge Decks
Publisher: American Society of Civil Engineers
Abstract: Transverse prestressing of bridge decks is an attractive concept with substantial benefits in both economy and improved durability. This paper summarizes a series of interrelated physical tests and computer analyses which ...
Effects of Duct Types and Emulsifiable Oils on Bond and Friction Losses in Posttensioned Concrete
Publisher: American Society of Civil Engineers
Abstract: Emulsifiable oils are often used in posttensioned construction to reduce friction losses and provide temporary corrosion protection for tendons prior to grouting. This paper addresses the effects of two emulsifiable oils ...
