Abstract: As a critical component of the national transportation network, bridges have received a lot of attention regarding their safety and condition state. Bridge superstructures begin to degrade after they are placed in service; ...

Abstract: The hybrid composite beam (HCB) system is an innovative structural technology that has been recently used in bridge construction within the U.S. transportation network. This investigation focused on evaluating the in-service ...

Abstract: This study explored the application of two-dimensional digital image correlation (2D-DIC) for measuring deflections of in-service bridges. Within the emerging area of image-based structural health monitoring, this work ...

Abstract: The functionality of the U.S. transportation infrastructure system is dependent upon the health of an aging network of over 600,000 bridges, and agencies responsible for maintaining these bridges rely on the process of ...

Abstract: Ultrahigh-performance concrete (UHPC) exhibits several properties that make it appropriate for the rehabilitation of concrete structures. In this investigation, the application is focused on bridge deck overlays, but the ...

Abstract: This paper presents the results of a live-load test of the Shenley Bridge, the first bridge application of the sandwich plate system technology in North America. The investigation focused on the evaluation of in-service ...

Abstract: Evaluating the condition of concrete bridge decks is an increasingly important challenge for transportation agencies and bridge inspection teams. Closing the bridge to traffic, safety, and time consuming data collection ...

Abstract: In response to rising energy costs, there is increased demand for efficient and sustainable transportation of people and goods. One source of such transportation is the railroad. To accommodate the increased demand, railroads ...
