Abstract: This paper describes the first application of Electrically Isolated Tendon (EIT) technology in the United States. These systems have been developed to provide a level of quality assurance for post-tensioned strand systems ...

Abstract: An experimental investigation was conducted to develop an effective means of connecting glass fiber reinforced polymer (FRP) bridge decks to conventional reinforced concrete parapets. Six full-scale subassemblies were ...

Abstract: This research study examines the use of a precast concrete panel system for blast protection of facilities with exterior light gauge metal stud walls. The structural retrofit is designed for the specific case where internal ...

Abstract: An investigation was conducted of unexpected damage to a pair of three-span continuous-spread prestressed box beam bridges after 12 years of service. Routine inspection had revealed cracks in the box beams near the piers ...

Abstract: An investigation was conducted on noncomposite prestressed precast concrete adjacent-box-beam bridges that suffered catastrophic failures resulting from the corrosion of the prestressing steel. These failures highlight the ...

Abstract: Intentional and accidental impulsive loads from high-explosive detonations and munitions can result in significant damage to both civil and military facilities. One demand scenario of particular concern occurs during ...

Abstract: To address the ever-increasing quantity of scrap tires produced in the United States, a study is conducted on the use of crumb rubber in concrete for enhancement of structures against blast effects. Crumb-rubber concrete ...

Abstract: To address the ever-increasing quantity of scrap tires produced in the United States, a study is conducted on the use of crumb rubber in concrete for use in structures against near-field blast and ballistic demands. Crumb ...

Abstract: On the evening of December 27, 2005 the fascia beam supporting the east side parapet wall of the third span of the Lake View Drive Bridge failed under the action of dead load. To gain insight into the potential causes of ...

Abstract: Tunnels are critical links within modern transportation networks and are susceptible to accidental explosion from vehicle fuel and cargo. They also present a target for terrorism due to unscreened public access. Roadway ...
