PCI eLearning Course T225: Case Studies and Emerging Developments of Full-Depth Precast Concrete Deck Panels-NUDECK Panel System for Nebraska's Skyline Bridge

NUDECK Panel System for Nebraska's Skyline Bridge

Pdf Summary

The article discusses the NUDECK system, a precast/prestressed concrete bridge deck panel system developed by the University of Nebraska-Lincoln. The system is designed to address the common problem of cracking and deterioration of concrete bridge decks. It uses high performance precast concrete combined with two-way prestressing to ensure continued compression of the deck during its service life.<br /><br />The article explains that the NUDECK system has several advantages over traditional cast-in-place concrete decks. It can be used for both concrete and steel bridges, and it results in significantly reduced construction time and traffic disruption. The system also provides a low-maintenance deck that is more durable and longer lasting than traditional decks.<br /><br />The article describes the design and construction of the Skyline Bridge in Omaha, Nebraska, which was the first implementation of the NUDECK system. The bridge consists of two spans and includes innovative features such as large diameter steel studs, a hanging support system, and a unique crown forming system.<br /><br />The article concludes by summarizing the main benefits of the NUDECK system, including its cost effectiveness, fast construction time, and superior durability. It highlights the success of the Skyline Bridge as an example of the system's potential impact on bridge construction and maintenance.
