Abstract: RC bridge columns that are at risk for collision loading must be designed for lateral impact load. Because bridge columns must also support axial loads, evaluating the residual axial capacity and collapse risk of impact-damaged ...

Abstract: Assessing the structural response and vulnerability of bridge piers to collisions by barges typically involves either the use of static pier analysis codes and design-specification-stipulated equivalent static loading ...

Abstract: RC bridge columns that are at risk for collision loading must be designed for lateral impact load. Because bridge columns must also support axial loads, evaluating the residual axial capacity and collapse risk of impact-damaged ...

Abstract: For bridges susceptible to barge collision, design provisions are typically utilized in determining collision scenarios and impact loading. Provisions in the United States require that bridges be designed to withstand two ...

Abstract: In the United States, barge impact-resistant bridge design typically involves static application of code-prescribed impact loads. However, the existing static analysis procedure neglects crucial dynamic effects in the ...

Abstract: Hurricanes produce high winds and heavy precipitation, causing widespread damage to infrastructure in coastal areas. Throughout low-lying coastal cities such as New Orleans, Louisiana, a network of constructed waterway ...

Abstract: Impact-induced loads associated with barge-to-bridge collisions frequently control the design of bridges spanning navigable waterways. To design for such loads, widely used bridge design standards use an approach in which ...

Abstract: The development of corrosion as a result of tendon exposure to moisture or corrosive media often leads to wire fractures. Such fractures in unbonded tendons are expected to induce global strand and anchor response through ...

Abstract: During bridge construction, the flexible support conditions provided to precast, prestressed concrete girders by steel reinforced neoprene bearing pads allow for a rolling motion about an axis parallel to the span of the ...

Abstract: This paper describes the development of a finite-element model capable of representing a blast-resistant flexible window (flex window) system developed by the Air Force Research Laboratory/Airbase Technologies Division. ...
